$SPY 250905 652 Put(SPY250905P652000.US) opened at $1.50,

$SPY 250905 651 Call(SPY250905C651000.US) opened at $1.55;

Pre-market at 09:08 am, it hit a high of $652.160, and I drew a horizontal line;

During the session at 09:49 am, it hit a high of $652.210. At this point, I should have bought $SPY 250905 651 Call(SPY250905C651000.US) at around $1.10,

But in reality, at 09:45:52 am, I modified the order to buy at $1.13 with a stop-loss at $1.01,

At 09:48:44 am, due to fear, I changed the order from 09:45:52 am to $1.05, just $0.01 away from the lowest price of that minute. Reflecting on this, I should have set the price to the lowest price at 09:45 am, which was $1.13, plus $0.10, making it $1.23. If the stop-loss at $1.01 was triggered, the loss would have been $66.00 plus fees,

At 09:50 am, as the price approached $1.22, I briefly considered placing an order but didn't execute it. Here, "taking a gamble with a stop-loss" wasn't executed well;

Summary:

1️⃣ Today, I waited until after 09:40 am to open a position, dismissing the alarm at 09:40, which aligns with the trading system (the reason for not opening a position before 09:40 today was the significant rise during the night and pre-market sessions, with the NFP data initially causing a drop before rebounding to a 52-week high),

2️⃣ Monitoring BTCUSD on Tradingview via iPad aligns with the trading system,
