I need help with translate code from tradingview Pine

One last question does the PRT backtest with hirstorical spread info, because TV only can add commission.. ?

I have the base code of BB + LSMA for prt but I need to insert more right conditions like DB and RSI.

// Définition des paramètres du code
DEFPARAM CumulateOrders = False // Cumul des positions désactivé

// Conditions pour ouvrir une position acheteuse
indicator1 = LinearRegression[19](close)
indicator2 = ExponentialAverage[224](close)-std[224](close)
c1 = (indicator1 CROSSES OVER indicator2)

IF c1 THEN
BUY 1 SHARES AT MARKET
ENDIF

// Conditions pour fermer une position acheteuse
indicator3 = LinearRegression[19](close)
indicator4 = ExponentialAverage[224](close)
c2 = (indicator3 CROSSES OVER indicator4)

IF c2 THEN
SELL AT MARKET
ENDIF

// Conditions pour ouvrir une position en vente à découvert
indicator5 = LinearRegression[19](close)
indicator6 = ExponentialAverage[224](close)+std[224](close)
c3 = (indicator5 CROSSES UNDER indicator6)

IF c3 THEN
SELLSHORT 1 SHARES AT MARKET
ENDIF

// Conditions pour fermer une position en vente à découvert
indicator7 = LinearRegression[19](close)
indicator8 = ExponentialAverage[224](close)
c4 = (indicator7 CROSSES UNDER indicator8)

IF c4 THEN
EXITSHORT AT MARKET
ENDIF
