bar's index limitation?

[gfuks1]

Hello.

I wrote a loop that calculates bars starting from index of bar -400,
and getsvalues of 10 bars each times, for example i did
getvalue of bar -400 to bar -390.

Problem is that when i try to start for example from bar -1500 the
program doesn't seem to work.

Please advice...

Hello gfuks1,

If bar index -1500 is not loaded in your chart, getValue() returns null. To ensure that the data is loaded into your chart, set up a custom time template to load the necessary data your formula needs.
