Ho provato a modificarla, ma non sono sicuro funzioni tutto correttamente, almeno per la parte di simulazione.

Fai delle prove:

defparam cumulateorders=false

once longontrading=0
once shortontrading=0
// --- strategy settings
tpratio = 2.7
stoploss = 65
takeprofit = stoploss*tpratio
 
// --- simulated trading settings
equityCurvePeriod = 20 //orders quantity for the equity curve average
activateSimulatedTrading = 1 //(0= false / 1 =true)
 
//strategies
buysignal = average[7] crosses over average[21]//rsi[2] crosses over 30
sellsignal = average[7] crosses under average[21]//rsi[2] crosses under 30
 
if realtrading then //real trading
if not longonmarket and buysignal then
buy at market
ordercount=ordercount+1 //counting the order to know we have sufficient ones to activate the simulation later
endif
if not shortonmarket and sellsignal then
sellshort at market
ordercount=ordercount+1 //counting the order to know we have sufficient ones to activate the simulation later
endif
set target pprofit takeprofit
set stop ploss stoploss
elsif not realtrading and ordercount>equityCurvePeriod then //fake trading
if not longontrading and buysignal then
openprice=close //fake order open price

endif

//reset MFE & MAE values
mfe=0

endif
endif

mfe = max(high-openprice,mfe) //compute the MaxFavorableExcursion
