For efficient clearing & settlement of trades, NDEX has an automated clearing and settlement system with NIBL Bank as its Clearing Bank. The software automatically calculates Initial Margins using VAR (Value at Risk) and MTM (Mark to Market) margins on a daily basis. In the same way, members’ positions are also computed on a daily basis. The information regarding pay-ins and pay-outs arising in calculations of positions of members is transferred at the end of trading hours electronically, using flat files for the clearing banks and members.
The objective of NDEX is to organize trading in such a way that possibility of defaults is almost eliminated. To achieve this, NDEX has adopted various means as follows.

Margin

  • Initial Margin  
    Initial margin is charged to participants for initiating buy/sell trades and is collected up front from the clearing members. Initial margin is based on the volatility of the future prices of underlying commodities and is subject to change intraday.
  • Fixing Minimum Initial Margin
    As per directives and rules of the Exchange , the VAR based Initial margin on all the commodities future contracts is subject to a minimum percentage defined per commodity as per contract specification.
  • Margin for Calendar Spread Positions
    Calendar spread position is defined as counter positions created by a client in two different expiries of a commodity. Calendar spread benefit is given to the members, as calendar spread positions are loss off-setting positions. (As contracts of same commodities tend to have similar price movement, because of this loss in one position of the spread is offset by profit in other position of the spread) Exchange will charge one half (1/2) of the Initial Margin on the 'Calendar spread positions', or at such rate as may be specified by the Exchange from time to time on the contracts identified for extension of Calendar Spread Benefit. The Exchange shall inform the members about the commodities not eligible for Calendar Spread benefit from time to time.
  • Tender Margin
    The Exchange may charge tender margins on contracts during the last 3-5 days of Expiry depending on contract specifications. Such margins are different for different commodities.
  • Delivery Margin
    The Exchange may charge delivery margin on all matched positions from the date of Expiry of the contract to the date of delivery settlement of the contract. The delivery margin percentage is different for different commodities.
  • Special / Additional margins
    The Exchange may levy additional margins as may be decided from time to time. These margins are over and above to the initial margin.
    • Unidirectional margins on long/short side are termed as Special Margins
    • Margins levied on both long and short side are termed as Additional Margins.
    • Removal of such margins is at the discretion of Exchange.
  • Regulatory Margins
    Any margin that is levied by the direction of the Regulator is termed as Regulatory margins. Such margins could be one sided i.e. either on long/ short or on both sides. Removal of such margins is at the discretion of the Regulator.
  • Failure to Pay Margins
    The Member who does not have sufficient funds in the Margin account to cover for various margins charged by the Exchange shall go into the square off mode. The member will remain in square off mode till the time he does not fulfill his margin commitments/or reduces positions such that the deposits are sufficient to make good the margin requirements.

    In Square off mode, member is not allowed to take fresh positions. However, member can log in to the terminal to square off his positions thereby reducing the margin utilization.The Exchange may charge penalty on violations of margin limits at such percentage as determined by the Exchange from time to time.

Mark to Market (MTM) Margins:

MTM is a mechanism devised by the exchanges to prevent the possibility of the potential loss accumulating to the level where the participants might willingly or unwillingly commit default. All trades done on the exchange during the day and all open positions for the days are marked to closing price for the respective delivery/contract and notional gain or loss is worked out. Such loss/gain is debited/credited to respective member’s account at the end of each day. The outstanding position of the members is then carried forward the next day at the closing price.

Mark to Market

Profit/loss for all the Members on all Open Positions is tracked real time by the Exchange and settled in cash on the next trading i.e. T+1 day. This process of settlement of profit/loss at regular interval is called Mark to Market.

All the open positions of the Members are marked to market at the end of the day and the MTM is    determined as below:

  • On the day of entering into the contract, it is the difference between the bought/sold value and settlement value for that day.
  • On any intervening days, when the member holds an open position, it is the difference between the daily settlement value for that day and the previous day's settlement value.
  • On the expiry date if the member has an open position, it is the difference between the final settlement value and the previous day's settlement value.
  • The MTM is settled in cash on the T+1 day. If T+1 happen to be a banking holiday, then MTM would be settled on next clearing day.


Benefits of Mark to Market:

Daily MTM settlement ensures, buyers/sellers settle their trades on a daily basis via a Daily Settlement Price (DSP).This means, even if on the expiry day, the Final Settlement Price (FSP) value is different from the entry value; the net settlement for the buyer/seller is based on their entry value.

The MTM of member is settled on a daily basis. This ensures that losses do not accumulate in members account at any point of time.

Monitoring of Mark to Market Loss:

The MTM pay-in of the Clearing Member is compared with the margin deposits to ensure that the MTM pay-in is always within pre specified limit. When the loss of a member increases beyond the pre specified levels, the system will automatically generate alerts at Trader Workstation.

In case the MTM loss reaches/goes beyond upper limit set by the Exchange, the Member shall go into the Square off Mode.

In square off mode, the member is not allowed to take fresh positions. The Member should immediately fund his pay-in account if there is MTM shortage which is resulting into Member receiving alerts and/or going into square off mode.

Position Limits

Position wise limits are the maximum open position that a Member and/or his constituents can have in any commodity/contract at any point of time. Such limits are different for different commodities/contracts. Position Limits are specified at Member and Client levels. The Exchange may specify different position limits for near month contracts. The position limits applicable on various contracts applicable at the client level and the member level will be announced at the time of the launch of the contract. Any change in these levels shall be intimated to members vide circulars of the Exchange.


Monitoring of Position Limits

Members/client breaching position limit shall be liable to pay penalty to the Exchange based on the directives of the Exchange from time to time. The violators of position limits will be accountable for their large positions and will submit detailed information pertaining to their trading activities whenever the information is sought by the Exchange.


Intraday Price Limits

For every commodity, the maximum price movement during a day is limited by the Price Limits prescribed by the Regulator. Price limits (upper and lower) are based on the previous day closing price of the contract and are prescribed in percentage term.

If the price band limit is hit intraday, Exchange will relax the price band limits to a higher     
level, as per the set procedures in accordance with regulation guidelines.
