Error on calling "On Bar Update"

[laocoon]

Hello,

I developed an indicator that compiles and runs fine. It draws arrows on the chart when certain conditions are met.
When I hit "Reload NinjaScript" however, the arrows that were there before dissapear.
Also, I get the following error message in the log (from the start): Error on calling "On Bar Update"method for indicator XYZ on bar 0. You are accessing an index with a value that is invalid since its out of range.

What should I do?

Thanks

Most likely you are doing something like "Close[0] < Close[1]" or whatever but you are not checking first if CurrentBar >= 1.

Try this - if you never index back further than [1] add this line at the top of OnBarUpdate: if (CurrentBar < 1) return;

That was very helpful, thanks a lot.
