NbarsDown backTest vs Replay

[johnchandler32]

Hi I have the following Condition set

If (NBarsDown (3, false, false, false) [-5] == 1

During back test i get some sort of result, During Market Replay i get no results whats so ever, no trades no orders.

Any Suggestions,
John

John, with the -5 for bars ago, are you trying to check 5 bars back? If so, try with just a 5 and not -5. The arguments you've provided are very flexible, so something should be happening. Are you sure there are actually 3 bars down that meet all the conditions on the Market Replay data you're replaying?

-5 and 5 produce difference results in backtesting. And yes all the conditions are met in market replay mode.

John, I'm not sure I follow you here - using a negative index would not be supported, please only use positive #'s here.

stupid Question here, but why cant i use a negative number? Hopefully i can have a better understanding.

There's simply no concept present for using negative numbers as we don't support accessing any series values in the future, at index 0 you're on the right most / currentbar from here you could only compare to values in the past so positive index values.
