If you’re missing a little bit and you experience slippage, then if it reaches you again, don’t take it—go to the next order. Orders are indeed being sent quite often. If you only want stable trades, only take the orders that have the key points marked. 2445 is short, and 2260 is long—both have annotations. If you want steady results, don’t place real-time orders; for real-time orders, you need to keep watching the chart.
