@caroy , I enjoy your journal and thanks for sharing.
Just some observations and thoughts, if you are okay with that:
1) You're trading a lot of symbols - you had 10 flies open on Thur for the overnight hold and opened another 6 on Fri for the intraday.
2) There are a lot of meme's, esp in the Fri intraday stocks, and these can move big/irrationally, thus blowing out the fly's profitability within minutes. You noticed how GME was hanging around the ideal 200 strike (your body) for most of the time, till about 15 mins before the close when it shot up to 209, turning a good profit into a big loss.
3) Not sure what time of the day you tend to close your trades, but "power hour" and certainly the last 15 to 30 mins of the trading day can see big moves. So maybe look at taking a smaller profit if one is available, earlier in the day? Esp true for less liquid stock, where spreads can widen and fills can be poor within the last hour.
4) I'm surprised at the narrowness of some of the fly's, eg SQ was only 5-wide (240-245-250). Am curious how you decide on the width?
5) Request - is it possible for you to post what the stock price was at the time you opened the trade? This would make it clearer whether the fly was ATM, or bullish or bearish.
Happy trading.
