how to deal with gap

[robinxing]

I think gap has great impact on the system

wether overnight system or intraday system

for example the original trend is down

but next day it gaps up

the price movement deviates from original trend

but after the gap up , the price drops down to a specific price

then the system short 1 contract

but at that moment,the price stops dropping

it moves up........................

the market sideways

under such situation,it is hard for trend following system

I wanna find some ways to deduce the impact of gap on the system

Is there any articles about the topic?

thank you
