I have modified the code,
how many spread do you need to do the backtest?

//DEFPARAM FlatAfter = 235500
DEFPARAM cumulateorders=false
DEFPARAM PRELOADBARS = 10000
ONCE positionsize=10
Once ministop=2



tradetime=time >080000 and time < 215000 and dayofweek<>0

timeframe (30 minute, updateonclose)

stdev=1
aa = average[100,1]
HBand = aa+average[200](std[100]*stdev)
LBand = aa-average[200](std[100]*stdev)

c1=close crosses over Hband and high>high[1] and summation[100](close>Hband)<65 //and summation[10](close>Hband)[1]<xx//and high<highest[4](high)[1]
cs1=close crosses under Lband and low<low[1] and summation[100](close<LBand)<65 //and summation[10](close<LBand)[1]<xx//and low>lowest[4](low)[1]
