thanks Zerodha. Now I am clear as to how the MTM works.
Just want to clarify what happens if a client has done some trading and the market moves in his favour or against him. I would like to give one scenario for both situations. Each scenario has two quesions. One for trading day and one for holding position overnight. So a total of 4 questions.
CASE 1) Favourable Movement.
Assumption: Client has booked all his trading money as margin to trade in futures (be it MIS or NRML).
In the example nifty went up by 1.67% (from 6000 to 6100), the margin required also went up by 1.67% (from 30000 to 30500).
Suppose someone has taken a position say in HUL. If the stock price moves up by 20% in one day, then the MIS and the NRML margins required would move up by 20%.
So if a client had X rupees blocked as margin previously. The new margins required would be Y = 1.2X, and X = 0.83Y. Which means that the initial margins submitted by the client (X which is his whole trading money) is now 83.33% of the margin required under the MIS or NRML product. Suppose this movement happens by 12.00 PM
I have put the below table which shows how the initial margins would decline if the stock price moves up from 5% to 30%.
05% increase - 95.24%
10% increase - 90.91%
15% increase - 86.96%
20% increase - 83.33%
25% increase - 80.00%
30% increase - 76.92%
50% increase - 66.67%
So what I want to know is that till when would the client be allowed to hold his positions during the rest of the day under MIS/NRML. and till what limit would the client be allowed to hold position overnight under NRML. I would give you my understanding on this issue which is as below and you can just tell me if I am wrong or correct:
For positions during trading day (COVER/MIS/NRML):
I would assume that a client having favourable position and thus having MTM profits would be allowed to hold his positions for the rest of day until 3.20 or 3.00 (please tell whether its 3.00 or 3.20?) for both NRML and MIS IRRESPECTIVE of whether the Market moves up (or down and the exchange increases the margin required due to volatility) by 05% or 50% and his margin required in the trading account drops from 100% to 95% to 66.67%.
1) So am I correct that a favourable trade (whether MIS/COVER/NRML) would be allowed to continue for the trading day (till 3.00 or 3.20 ?) irrespective of how much the client's initial margin has declined due to an increase in margin from the exchange, and that there would be no auto square off or margin call till end of trading day. Please tell if I am right in my understanding?
For holding the position overnight (for NRML):
Now once the client gets the MTM credited next trading day, the client would definitely have cover for his increased margins. But for the end of today's trading day the client will be short of margins by 3.20 PM. So say the client has new margin requirement of 130,000 and the client has 100,000 in his account and 300,000 in his MTM profits. So the client has 76% of the margin required under NRML but 300,000 in MTM profits.
2) So in this case how much % margin is sufficient to hold the positions overnight? will the client be asked for full 100% (130000) to hold overnight or will he be allowed to hold with say 90% (117000) or 80% (104000) or will he be allowed to hold with 76% itself (100,000) considering that next day he would have 400,000 in his trading account.
CASE 2) Unfavourable Movement.
Assumption: Client has booked all his trading money as margin to trade in futures (be it MIS or NRML).
for trading day (MIS/NRML):
3) The client has MTM losses. The margin required for MIS/NRML in the account has decreased. So if it is 100% margin required originally under MIS/NRML. The client account margin is now reducting to 95%, 90%, 85%, 80%. Till when would the client be allowed to hold position during the trading day till 3.20 or 3.00 PM?
For overnight (NRML):
4) The client has MTM losses. The overnight margin required is 100%. The client has say 98%, 97%, or 95% or 90%, or 85% of the overnight margin. Till what decrease will the client be allowed to hold his position overnight?
Thanks.
