Grid bot "Expiration Reason: Insufficient margin account balance" WTF?

Ok so this is the state of affairs I found myself this morning.

I awoke with a message from binance telling me that my eth/usdt grid bot was stopped for "Expiration Purpose: Insufficient margin account stability" so i took a very good loss.

Apparently in the course of the night time the worth of eth went up and the bot started to open brief position at each grid making clearly a unfavorable PNL then ready for the worth to return down for closing those shorts. I do not know why this happened, earlier than I went to bed my margin ratio was zero.22 and the liquidation worth of the grid was at 2900$ so I assumed that I used to be protected (apparently not).

My bots details are:

Mode
Geometric

Perhaps I want more collateral in my cross future wallet? However how? My margin ratio, the upkeep margin and the margin stability have been high-quality. I don't know why this occurred and how one can forestall this from occurring once more in the future.
