Setting a Variable

[bendjo]

Hi Support,
if I set a variable (previously declared as private double variable1 = 0; in the Variable section) to a fixed value at the time I enter a trade in the onBarUpdate() method as described below

if(Close[0] > Close[1])
{
[B]double variable1 = High[0] - Low[0]; [/B]
entryOrder = EnterLongLimit(0,false,1,Close[0],"Buy"); 
}

for how long does this variable maintain the value stored (e.i. High[0] - Low[0] of the bar i entered)?

Assuming after 10 bars in the trade I call this variable to adjust my stop (code below), would this be still the same value set at the time I entered the trade?

if(Close[0] > High[1] + [B]variable1[/B])
stopOrder = ExitLongStop(0,true,1,Close[0]+variable1,"TrailingStop",Buy");

Hi bendjo,

The value of the variable will be retained until it is reset. In your case, it will be reset for each bar where Close[0] > Close[1]. So, if you want to retain the original value and NOT reset it every time the condition is true, then you'll need to add some additional logic to prevent that block of code from executing. For example:

Close[0] > Close[1] && position.MarketPosition == MarketPosition.Flat

which will prevent the variable from being recalculated when you're currently in a position.

well received thanks. I guess it work the same with something like this:

if(Position.MarketPosition == MarketPosition.Flat)
{ if(Close[0] > Close[1])
{
...
