By the way, I thought the depth of my position shouldn't be an issue, but closing MU at market price with 3M turned 10wu profit into 49000u. That drop from 998 to 970 at 11:12 in one minute was caused by my closing. Weekend depth really isn't great. I treated MU like Hynix and closed it without paying attention. Sigh, if there were some kind of price spread alert, like on Dex or instant swaps, giving a warning for excessive spreads, I wouldn't have lost hundreds of thousands.
