Let me explain, since you’ve pledged stocks for margins, you receive a margin credit against them. However, the effect of margin you receive from stocks doesn’t show up on the ledger as a credit. This is why you’re seeing the withdrawal amount higher than the available amount.
In the example you’ve given:
You’ve taken a position for which margin required = 80,000
Margins available:
In the form of cash = Rs.1,00,000
In the form of collateral = Rs.1,00,000
Total margins available = Rs.2,00,000
Of the 80,000 margins required for your carry forward position, we’d block 50% of it in the form of cash and expect the other 50% to come by way of collateral. So, from the 1,00,000 cash & collateral margins of 40,000 each would be blocked towards the position where margins = Rs.80,000. This leaves you with a withdrawal balance of Rs.60,000 (1,00,000 cash - 40,000 margins). The account balance however would show 20,000 (1,00,000 cash - 80,000 margins).
Having said this, I understand your concern. We’ll work towards making the withdrawal page intuitive.
We’ll take your feedback and do our best, one thing that we’ve already done to address this issue is: when you place a withdrawal request for amount greater than what you can withdraw, your request gets rejected. You’re immediately sent an SMS informing you of the rejection along with the details of the amount of money you can actually withdraw. You get a 60 minute window within which time you can come back and place another withdrawal request which will get processsed the same day. In parallel, we’re also working on instant withdrawals, it had to go live but got delayed due to the prevailing situation.
