Need help: Looping multiple sets of data through a calculation...?

[HODL-Lay-HE-hoo!]

I need some direction for the following:

Currently I am using a trailing stop strategy / study with multiple duplicates (in a single study with a suffix added to the variables and whatnot) for backtesting.

I would like to take a code similar to this:

def profitLoss;


if (!isOrder or orderPrice[1] == 0) {
    profitLoss = 0;
} else if ((isOrder and isLong[1]) and (SellSig or BuyStpSig)) {
    profitLoss = close - orderPrice[1];
} else if ((isOrder and isShort[1]) and (BuySig or SellStpSig)) {
    profitLoss = orderPrice[1] - close;
} else {
    profitLoss = 0;
}


#And instead of copy pasting it ten times create a list for each variable:



def sellsignallist = {SellSig_1, SellSig_2, SellSig_3, SellSig_4}

etc...

then have each of those loop through the code for profitLoss without having to have 1000 lines of code...

I am having some technical difficulties figuring out how to achieve this... any help would be appreciated.

maybe this sub script will give you some ideas.
it is not complete, just a framework.

# put sub scripts first in study


script sellx {
input isOrder = 0;
input orderPrice = 0;
input isLong = 0;
input isShort = 0;
input SellSig = 0;
input BuyStpSig = 0;
input SellStpSig = 0;


def profitLoss;
if (!isOrder or orderPrice[1] == 0) {
profitLoss = 0;
} else if ((isOrder and isLong[1]) and (SellSig or BuyStpSig)) {
profitLoss = close - orderPrice[1];
} else if ((isOrder and isShort[1]) and (BuySig or SellStpSig)) {
profitLoss = orderPrice[1] - close;
} else {
profitLoss = 0;
}


# this doesn't plot anything. it just sends a number out, back to the  sellx() function that called it.
plot z = profitLoss;
# end of script
}


# main formulas
def isOrder1=
def orderPrice1=
def isLong1=
drf isShort1=
drf SellSig1=
drf BuyStpSig1=
def SellStpSig1=

def isOrder2=

def isOrder3=

drf isLong3=
def isShort3=
def SellSig3=
def BuyStpSig3=
def SellStpSig3=


# copy this for all the different sets of variables
# send data to the script sellx() to calc a number

def a1 = sellx(isOrder1, orderPrice1, isLong1, isShort1, SellSig1, BuyStpSig1, SellStpSig1);

def a2 = sellx(isOrder2, orderPrice2, isLong2, isShort2, SellSig2, BuyStpSig2, SellStpSig2);

def a3 = sellx(isOrder3, orderPrice3, isLong3, isShort3, SellSig3, BuyStpSig3, SellStpSig3);

Thanks! I’ll look into it.
