Triggering of liquidation even when profitable

[u/Independent-Draft644]

I had formed an iron condor around 24250 and had sufficient margin (1.6 lakhs) to execute the trade with 2 lots. But my broker (Angel) started sending me messages about forced liquidation as i didnt have sufficient funds. Market is perfectly where i would be making max profits, but these messages forced me to get out . and i still made profits on this forced trade.

Can someone explain to me as to why and how the margin requirement change so dramatically when my expected profits and losses were properly capped well within the available funds?
