Error on bar -1 ??

[After]

Hey guys,

Sometimes I get this error in the log : Error on calling "OnCalculateMinMax" method on bar -1 : the calculation results in unrenderable values.

How is it possible to have an error on bar -1 if I start the calculation from the Bar 50 (with if CurrentBar>50) ?

Thanks !

Hello After,

Thanks for your post.

It may be that you are calculating an index position and the index is getting set to -1. To start debugging, you can add print statements to your code to narrow down where the coding issue is.

Thanks for answering Paul,

"It may be that you are calculating an index position and the index is getting set to -1"

What do you mean by "index position" ? Could you show me an example ?

Thanks !

Hello After,

Thanks for your reply.

An example maybe where you are looking for a High 51 bars ago High[CurrentBar - 51].
