OTC Clear to its Clearing Members to manage the collateral holdings and obligations with OTC Clear. 

This OASIS Web Portal User Manual aims to enable the Clearing Members of OTC Clear to make full 

and efficient use of OASIS by providing instructions for using the system's functions (input, enquiry 

and report retrieval). 

All instructions and activities in OASIS are subject to the respective Rules and Procedures of OTC 

Clear. 

Contents 

The Web Portal User Manual covers all available functions on OASIS. It is divided into two following 

parts: 

Part I: 

• General & System Related Information of OASIS

2. System Overview 

2.1. Framework Overview 

The following diagram shows the connectivity between OTC Clear’s Clearing System (OCASS) and 

OASIS.

OTC 

Clearing 

System 

(OCASS) 

Margin Simulator

Collateral 

Management 

Portal 

SDNet Network 

Environment 

Clearing Members’ PC 

OASIS connection framework 

As shown in the diagram, Clearing Members need a PC (dedicated PC is recommended due to 

security concern) connecting OASIS via the Securities and Derivatives Network (SDNet). 

SDNet is a consolidated network infrastructure designed to support multiple market system networks. 

Currently, SDNet supports many of the existing market systems of Hong Kong Exchanges and 

Clearing Limited (HKEx) including the Hong Kong Futures Automated Trading System (HKATS) and 

the Derivatives Clearing and Settlement System (DCASS). Please refer to “Section 3 Technical 

Requirement” for application and the installation details. 

After completing the installation of SDNet and connection to OASIS, Clearing Members will be 

provided with two URLs, one for logging on to collateral management portal and another for margin 

simulator portal. 

2.2. OASIS Operating Hours 

The operating hours of OASIS are: 

7:30 a.m. to 11:00 p.m., every OTC Clear Clearing Day 1 

Please note not all functions of OASIS are available throughout the operating hours. A number of 

functions on OASIS have different operating hours and are detailed in the corresponding sections of 

PART II. 

1 means, at any time, each day appearing on the OTC Clear Clearing Days Calendar that is in effect 

at such time 


2.3. Functions and Key Features 


OASIS has the following main functions to facilitate Clearing Members’ daily operations: 

Collateral management portal 

• Maintenance Functions 

o Submit collateral deposit/withdrawal requests 

o Fulfill margin calls requirement 

• Enquiry Functions 

o Enquire collateral account movement 

o Enquire the status of collateral deposit/withdrawal requests 

o Enquire margin calls 

• Reporting Functions 

o Retrieval of various types of reports 2 , including: 

• Trade reports 

• Settlement reports 

• Margin reports 

• Market Data reports 

Margin simulator portal 

• Simulation Functions 

o Simulating margin requirement for a single trade 

o Simulating margin requirement for a portfolio 

Key features of the two portals: 

Collateral management portal 

• An interactive web browser terminal providing online input, enquiry and report download 

via a secured network 

"Maker-Checker" mechanism to ensure collateral deposit / withdrawal requests are created 

and approved by different users. 

Margin simulator portal 

• Clearing Member-friendly interface allowing users to manually input trade details or adopt 

“bulk upload” (for portfolio) approach for margin simulation 

• Display margin requirement before and after the simulation for easy analysis of the impact 

to the existing portfolio 

2 Please refer to the Report Usage Guide for more details on the specifications of each report 

published by OTC Clear, the guidance for interpreting the contents therein, and the frequency of 

publication of each such report. 



3. Technical Requirements 

3.1. Connection Requirements 

Clearing Members are connected to the OASIS through Securities and Derivatives Network 2 

(SDNet/2) infrastructure. SDNet/2 is provided by different network vendors to the Clearing Members. 

HKEx has defined a set of commercial and technical requirements for the SDNet/2 infrastructure. 

Through a comprehensive accreditation process, initially, 3 vendors have been appointed to provide 

SDNet/2 network services. These Accredited Vendors are (in alphabetical order): Hong Kong 

Telecommunications (HKT) Limited (also known as PCCW), Hutchison Global Communications 

Limited (HGC), and Wharf T&T Limited (Wharf T&T). 

To apply for SDNet/2, Clearing Members should first approach the Accredited Vendors and get the 

SDNet/2 application form and information. The Accredited Vendors’ contact numbers and email 

addresses are set out in the SDNet/2 Information Pack. Clearing Members should compare offers 

from the Accredited Vendors, read carefully all the terms and conditions as specified on the 

application form and the relevant material before completion of the application form. For general 

enquiry on the application process, interested party can contact the technical hotline in Part I section 1. 

Clearing Members may apply either single link connection (without resilience) or dual links connection 

for their backup site. However from system resilience perspective, dual links connection should be 

installed for the production site. The bandwidth requirement for 1 to 2 concurrent OASIS user(s) is 

1M and for 3 to 4 concurrent OASIS users is 2M. Also, OASIS users should access the portal via 

SDNet/2 using a dedicated PC. Clearing Members should ensure the security of information 

transmission and LAN switch for dual links or multiple dedicated PC connections. 



The following two diagrams show the dual links and single link connection communication network 

setup. 

Option 1: Dual links connection 

Remark: Hub is required for dual links connection. 



Options 2 : Single link connection 


3.2. Software Requirements 

OASIS Users’ PC specifications: 

Recommended configurations for an OASIS user PC are as follows: 

Items 

Descriptions 


Hardware 

Configuration 

For MS Windows 7 Professional: 

- Processor: Intel Core i5 2400 /3.1GHz 

- Memory: 4GB 

- Local Hard Disk: 500GB 

Software 

Configuration 

Operating System (OS): 

- MS Windows 7 Professional 

- Browser: Internet Explorer 8.0 (IE 8.0) 

- 

3.3. Computer Virus / Worm Security Measures 

Computer virus or worms are one of the concerns in the security measures of computer system. 

Various security measures have been employed in OASIS to protect it from computer virus or worms 

attacks. Besides, there are other potential sources of computer virus or worms e.g. use of external 

storage device in Clearing Member's PC for downloading OASIS information or uploading files to 

conduct simulation. Clearing Members should take the following precautionary measures for the 

OASIS users' PCs: 

Virus protection 

Install anti-virus software on OASIS users’ PCs and regularly update the virus definitions from the 

vendor. 

If OASIS user is using a dedicated PC without Internet connection, in some case, the vendor may 

make available the definition files daily in the Internet for download. Clearing Members may download 

the updated virus definition file with a PC with Internet access, save the file in a disk or flash disk and 

install the update at the OASIS users’ PC. 

Microsoft OS patch 

Regularly review and install the latest Microsoft security patches in OASIS users’ PCs. Clearing 

Members may subscribe to Microsoft technical security notifications to keep up-to-dated about 

security vulnerability and patches available. 

If OASIS user is using a dedicated PC without Internet connection, Microsoft security patches can be 

downloaded from Microsoft Download Center (or Microsoft Update Catalogue) separately with a PC 

having Internet access. Clearing Members may then save the file in a disk or flash disk and install the 

patch. 

3.4. Prohibited Actions on OASIS System 

Clearing Members must not perform any unauthorised access or security scanning (no matter at 

network, system or application level) on OASIS and any related network device not owned by them. 

Any such attempt will be regarded as illegal access or malicious intrusion to OASIS. 



4. Access Control and User Account Management 

4.1. Access Control 

OASIS provides different access rights to ensure that only relevant information is accessible to the 

authorised users of Clearing Members. These include: 

• Clearing Member ID 

• User profile, which includes: 

• user ID 

• user access level assignment 

Clearing Member ID 

OTC Clear assigns a Clearing Member ID to each Clearing Member upon the approval of its 

membership. It is a twelve-character code. 

Example: ABCDBANK001T 

User ID: 

A Clearing Member may delegate its OASIS operations to a maximum number of four internal staff 

("OASIS users"). A unique user ID is assigned to each OASIS user by OTC Clear. It is an eightcharacter 

code (e.g. ABCDHK01 or ABCDHK02), of which the first six characters are identical to the 

Clearing Member ID. HKEx has the right to suspend or delete the user ID of an OASIS user. 

User Access Level Assignment: 

Currently there is only single access profile type offering to Clearing Member. Please refer to Table 

4.2 for the function available for different OASIS user access groups. 

4.2. User Account Management 

User Access Level Assignment: 

There is only single access profile type offering to Clearing Member. Please refer to Table 4.2 below 

for details. 

Clearing Members can apply OASIS users account by completing and submitting “OASIS User 

Account Maintenance Form” to OTC Clear. The form is available for download on the HKEx website. 

Upon the approval of the OASIS user account, each OASIS user will be assigned a unique User ID 

and password to logon to OASIS. Clearing Members are required to collect the initial passwords of 

the OASIS users in person at OTC Clear office and change the password at the first logon and every 

90days.

functions, there are system validation in place that same Operator cannot perform both Maker and Checker 

functions on the same collateral deposit / withdrawal request. This is to ensure dual level validation to be 

performed for all collateral deposit/ withdrawal requests. 

Clearing Members' Responsibilities 

Each Clearing Member is responsible for informing OTC Clear of any subsequent changes to the list 

of authorised signatories in relation to any request to OTC Clear for OASIS access. 

It is the responsibility of each Clearing Member to control the access to OASIS by ensuring the 

security and confidentiality of the User IDs and passwords of its assigned users. Clearing Members 

shall be liable for all instructions inputted into OASIS via the OASIS Users ID assigned to them. 

If the OASIS user forgets his/her password, the Clearing Members should contact OTC Clear to reset 

the password and Clearing members are required to collect the new password in person at OTC Clear 

office.

2. Collateral Management 

The following section explains how Clearing Members can use OASIS to manage their collateral balance with OTC Clear. The below table lists out different scenarios 

with consequent actions to be taken by Clearing Members: 

Scenarios Descriptions Actions required 

End-of-day Initial Margin Call 

– fulfilling the margin call in any 

eligible currency 

If required, the demand will be issued at 08:30 Hong Kong time on an 

OTC Clear Clearing Day via the Margin Calls function on OASIS. 

Clearing Member needs to fulfill the obligation in cash in any eligible 

currency. 

If member wants to settle the call in base currency 

(i.e. HKD): 

No action needs to be done on OASIS. 

The Clearing Member effect the payment through 

the Real Time Gross Settlement (RTGS) system to 

OTC Clear’s designated bank account. 

If member wants to settle the call in non-base 

currencies: 

Follow the process described in Appendix 4. 




Note: The status of the margin call will be updated 

upon confirmation of the receipt of the payment. 




Routine Intra-day VM Call 

– fulfilling the margin call in the 

preferred currency (“Intra-day 

VM Currency). 

If required, the demand will be issue at the Routine VM Call Time on an 

OTC Clear Business Day via the Margin Calls function on OASIS. 

Clearing Member need to fulfill the obligation by depositing collateral in 

the preferred currency within an hour following the Routine Intra-day VM 

Call. 

Note: For intra-day VM calls, clearing members can use the column of 

“available collateral” and “used” in WEB ERSCollateral report published 

at 1:30 p.m (after portfolio novation is completed) to estimate the call 

amount.. Below are two examples to provide call details: 

Scenario 1 – no trade is cleared today. In this case the margin call fully 

reflects the change in collateralized variation margin (i.e. PnL movement 

during the day)

Guarantee Fund Call 

If required, the demand will be issued via the Margin Calls function on 

OASIS. The timeframe of triggering ad hoc vm call will be from 08:30 HK 

local time to 15:00 HK local time unless further notified by OTC Clear. 

Clearing Member need to fulfill the obligation by depositing collateral in 

contractual currency within an hour following the Margin Call.

If required, the demand will be issued either at 08:30 Hong Kong time, 

14:15 Hong Kong time or other time specified by OTC Clear via the 

Margin Calls function on OASIS. 

Note: pursuant to OTC Clearing Hong Kong Limited Clearing Procedures 

7.5, OTC Clear may request a Clearing Member to post additional 

Collateral when the value recorded in the Rates and FX Contribution falls 

below the Rates and FX Liability (i.e. a drop in market value due to FX 

movements on a non-HKD collateral placed by a member). Such request 

will be in the form of a GF call which could be triggered at 8:30 a.m. or 




OTC Clear’s designated bank account 


upon confirmation of the receipt of the payment 

The same as actions required for EOD IM Call. 




(i.e. HKD): 




OTC Clear’s designated bank account 





2:15 p.m. In this case, the Clearing Member may see 2 margin calls at 

the same time on OASIS (one for IM account and one for GF account) 

and both calls have to be settled within 1 hour. Settlement methods for 

such GF call will be the same as routine Intra-day VM calls.

2.2.2. IRS What-If Trade – How to Use (Step by Step) 

1. Click What-if Trade in the operations panel. The panel will expand and display the trade templates 3 available to the user. The templates specify the 

currency and direction of the trade(s) for which the incremental margin requirement is to be simulated. 

3 Please see Appendix 2 for the template information 



2. Quick view: hovering over the template name with your mouse to have a quick view on template information. The attributes shown with a yellow star in 

the quick view are fields that can be inputted by users. 



3. Select the appropriate template to simulate margin requirement of the What-if trade. Input relevant information/data in the fields. All fields are 

mandatory. 



4. Select the account in which the new trade will be included (i.e. user’s Clearing Member account) from “accounts” drop down menu 

5. Select “HKEx” from “exchanges” dropdown menu 

6. Select “OFFICIAL” from “environments” drop down menu 

7. Click the launch report icon to request an incremental margin check for the new trade 

Gentle Reminder: 

Please make sure the correct margin date is selected. The margin date should be the previous business day on which the margin report has been 

generated. 



The report will take some time to generate. Once the calculations is completed, the simulation report will be displayed on the function screen. An 

illustration of the margin report is shown below: 

The report shows the differences in margin requirement of the portfolio before and after the new trade is included. The difference is color coded: 

Red: increase in margin requirement after adding this simulated trade

Appendix 4 — Additional Features to settle margin call in non-base currency 

Currently, OTC Clear will automatically issue the margin call (EOD Initial 

Margin (“IM”) call and intra-day margin call) in base currency (HKD). The 

following procedure is to facilitate and provide guidance on settling 

margin call in both base and non-base currencies (in normal days or 

currency holidays): 

1. EOD IM Call at 8:30 a.m. HK Local Time 

Case 1: Settle in base currency (HKD) 

Member can refer to “WEB ERSCollateral report” (generated on End of prior day) to retrieve 

the (indicative) IM call amount in base currency (if any) in advance. On next day morning 

member will see the actual call information shown in OASIS and use RTGS to settle HKD. 

Case 2: Settle in non-base currency 

In this case, member has to determine minimum amount of settling margin call in non-base 

currency: 

Step 1 - Member opens “WEB ERSCollateal report” and check aggregated collateral in HKD 

and Initial Margin (published on end of prior business day) 

Step 2 – Member uses the FX rates (member is advised to settle margin call in USD as “7.75” 

– the lower bound of USD/HKD FX rate can be used as a conversion rate. Other FX rates (e.g., 

EURHKD, CNHHKD) can be provided by OTC Clear via email upon request from members) 

and check “WEB IM Collateral report” (published on 1 st portfolio novation cycle – i.e. roughly 

8:30 a.m. HK local time) for haircuts information. 

Step 3 - Member uses the following formula to manually calculate equivalent call amount 

(Here we use USD as an example) 

[(Initial margin - Aggregated Collateral in HKD) / USD FX rate] / (1 – USD haircut) 

The minimum margin call amount (to be settled) in USD equivalent will be: 


107 

Page 101 of

[(1,188,186.28 – 19.6) / 7.75] / (1- 0.5%) = 1,194,137.37 (USD) 

Step 4 - Go to ‘MARGIN CALLS’ menu of OASIS 

Step 5 - Click ‘Quick Actions’ button, 

Step 6 - ‘New Mandatory Deposit’ function will pop out and click it 


Step 7 - Select ‘Cash’ and click ‘Next’ button 

Step 8 - Select the relevant currency as what you determine in Step 3 


107 

Page 102 of


Step 9 - Input the particular amount as what you determined in Step 3 and click 

‘Next’ button 

Step 10 - Click ‘Finish’ button and then perform 4 eyes check once you got the 

below message. 

Step 11 - Perform 4 eyes check once you got the below message. 


107 

Page 103 of


Step 12 – Member uses RTGS to settle the converted amount calculated in step 3. 

2. Intra-day margin call at 2:15 p.m. HK Local Time 

Case 1: Settle in base currency (HKD) 

Step 1 - Member opens “WEB ERSCollateral report” (the one published on 1:30 p.m. HK local 

time) to check “Available collateral” and “Used”. 

Or alternatively, they can wait for monitoring the intraday call information in OASIS (if any) 

to be published on 2:15pm. 

Step 2 – Settle via RTGS for the amount shown in above before 3:15pm. 

Case 2: Settle in non-base currencies 

Member should follow the procedure below to calculate equivalent call amount (Here we 

use USD as an example). 

Step 1 - Member opens “WEB ERSCollateral report” (the one published on 1:30 p.m. HK local 

time) to check “Available collateral” and “used”. 

Or alternatively, they can wait for monitoring the intraday call information in OASIS (if any)

if member’s collateral pool contains all types of collateral then member can refer to “WEB
