description: "$SPDR S&P 500(SPY.US) I recently saw foreigners applying their unconventional methods in options gamma to playing expiration dates, really envious. They knew the SPX7400 level within 15 minutes of market open.If I can secure a data source, I'm itching to develop one too, focusing on just one trade a day. The only thing missing is orders with deep ask/mid quotes. I currently have an account purely for the buy side, with a win rate of 68%. I wonder what level that is in the eyes of high-level experts. Lately, I've been fascinated by market maker hedging research. Any knowledgeable bros, let's follow each other and exchange ideas when we have time 🥳🥳"
