Generic Broker functions

[Emalv]

Good morning,
I would like to have an help from you. I translated this code from easy language. It runs and I could test it, but since I relayed the function "strategy.dolong" with "buyatmarket", the code doesn't read the exit rules and, if the initial condition is still true, it buys again.
What it doesn't work in this manner? How I should modify the code with the generic broker function? Could you make an example?
I paste only the incriminated part for the long version.
Thanks.
Enrico

var vSMA40 = new MAStudy(40, 0, "Close", MAStudy.SIMPLE);

function main() {
var Dev = StdDev(40);
if ((Strategy.isLong() == false) &&
close() >= vSMA40.getValue(MAStudy.MA) + 2*Dev)
{
// Long entry
Strategy.doLong("Enterlong", Strategy.MARKET, Strategy.NEXTBAR, Strategy.DEFAULT, 0);
}

else if (Strategy.isLong() == true && close() < vSMA40.getValue(MAStudy.MA))
{
// Long exit
Strategy.doSell("Exitlong", Strategy.CLOSE, Strategy.THISBAR, Strategy.DEFAULT, 0);
drawShapeRelative(0, high() + (high() - low())/4,
}

The Strategy functions are intended for Back Testing only. When processing real time data and/or using Broker functions you need to replace the Strategy calls [ie Strategy.isLong() in your example] with your own global variables that you will use to keep track of the position status of the system (see example below)

var IsLong = false;
 
function main(){
 
    if(IsLong == false && close(0) >= vSMA40.getValue(MAStudy.MA) + (2*Dev)){
        buyMarket(getSymbol(), 1, "YourBrokerTrade");
        IsLong = true;
    }
    if(IsLong == true && etc etc){
        sellMarket(getSymbol(), 1, "YourBrokerTrade");
        IsLong = false;
    }
