The opinions expressed in these forums do not represent those of C2, and any discussion of profit/loss is not indicative of future performance or success. There is a substantial risk of loss in trading. You should therefore carefully consider whether such trading is suitable for you in light of your financial condition. You should read, understand, and consider the Risk Disclosure Statement that is provided by your broker before you consider trading. Most people who trade lose money.
I’m looking at some of my fills placed at the open and they are off
AAPL for example shows a fill in C2 at 12.00 yet my Thinkorswim platform shows a trade placed at that same strike for 9.80 at 9:32:26 AM and another for 10.00 at 9:33:26 AM. Price wasn’t anywhere near the price C2 filled
My advice: don’t trade options in the first 30 minutes after the market opened. You will be rundown by the freight train of machine orders. The fills are never going to be accurate. Just let the algos set the prices and then 10.30-11 am place a limit order. Life will be good.
