most simple strategy: timing

buying the NQ every day at 10 am expect wednesday and hold till close gained on backtest 90K for the last 6 month

shorting the NQ from monday or tuesday close on a market above 200 ema and not rising

and holding the position till next day
10 - 11 am

showed some nice profits.

Simply look at prior week during which days the biggest gaps happend then use this knowledge to plan the week ahead.

הערה:

somehow no strategy executions are shown on the chart,
but backtest is for shorting monday and tuesday closing to the next day 11 am
