Some queries regarding the new margin rules

[Avi_Garg]

In the other thread that I posted, you said that Zerodha follows the system of collecting 50% of contract value on Wednesday and Thursday for ITM options.
Here -

Regarding margin requirements for long options nearing expiry

These margins are applicable only on Long ITM Options and are collected in phased manner from expiry minus 4 days. It is still the same, for Long ITM Options, 50% of contract value is blocked on last two days of expiry.

So, which one is it? Please clarify.
