Index was outside the bounds of the array.

[judysamnt7]

Hi,
the following code is simple and straighforward. But there is always an error saying "Strategy 'MyCandleStopInStopOut': Error on calling 'OnBarUpdate' method on bar 20: Index was outside the bounds of the array." Does anybody know why ? And the error seems to be from bar 20 onward.
Thanks !

if (CurrentBar < 20)
return;

if (Close[1] > Open[1] && Value[0] > High[1]
EnterLong(1, "Long Entry");

Hello judysamnt7,


From only that code I dont see what would cause that. do you know what specific line is having a problem? You can use Print statements to see how the logic is executing.

The purpose of this code above is to Enter a long order once current bar value goes above the previous bar's high, while previous bar is a green bar .

Hi Jesse,
I believe the following line caused the out of bound of index error.
if (Close[1] > Open[1] && Value[0] > High[1]

[judysamnt7]

If I replaced Value[0] with Close[0], the error will be gone. Kind of weird.

But what I really want is to check the real time price of current bar instead of close price. In this case, Can I still use Value[0] to get the tick by tick price of current bar ?

Hello judysamnt7,

You may need a currentbar check:

if(CurrentBar < 1) return;

To know the realtime price you would need to use OnEachTick or OnPriceChange in realtime, that would let you see the Close[0] price as the realtime price.
