check Series value at specific index

[ttodua]

i.e. in indicator I have

AddDataSeries("xyz", same, same);

and I use:

if ( Closes[0][0] > Closes[1][0])  ....

however, on main chart, if i am on bar (at 2010 year), the secondary data may not yet be available (i.e. if secodnary data starts after 2011 year).

so, indicator fire error "accessing the index that doesnt exist"...
so, i wanted to find a way to check if Closes[1] had an available index at 0, however such codes doesnt work:

if(Closes[1].IndexOf(0) ) ......

because Closes[1] doesnt contain any overload of IndexOf.

how can i check if specific index is loaded at this moment?
prbably you understand my problem.

Hello TazoTodua,

Thank you for the post.

The generally accepted way to check for data is to use the CurrentBars object:

if(CurrentBars[0] < 1 || CurrentBars[1] < 1) return;

This would ensure that both series have at least 1 bar to be used. By adding this type of check, that should allow logic which uses both series to occur.

I look forward to being of further assistance.

i used this code:

for (int bIdx=0; bIdx < BarsArray.Length; bIdx++) if ( CurrentBar - 1 <= BarsArray[0].Count - BarsArray[bIdx].Count ) return;


so your code is more easier (achieving the same) right?
will that handle in both of these cases, and wont throw the error, right?




thanks ! ! ! ! ! !

Hello TazoTodua,

Without printing out what you are doing, I couldn't say if that is specifically working the same. The CurrentBars object wont throw an error unless you use an index that is not there. Also, the Count property can be variable depending on the scripts settings and is also unknown when using TickReplay.

I would suggest trying my suggestion in place of the check you are now, and that would let you know if that solves the problem with your specific question. If it does not, we could look at a greater sample together to see why that may be.

I look forward to being of further assistance.
