ATR indicator print value error

[elliot5]

The chart value for the ATR is 2x the value I get from printing the value from the strategy to output. I use an array with multiple instruments and printing the value gives wildly different result from the chart value based on the same session template. It matters because I use the ATR for volatility calc for size adjustments.

Hello elliot5,

Thanks for your post.

I would suggest printing out the ATR values that are being determined along with the BarsInProgress from your script to ensure that what is being pulled from the script is correct. Conversely you may want to create a single series script to see if that single series also does not match the chart ATR.

I found the error. Strategy BarsToLoad was set at 5 - should have been 100. Simply did not have enough bars loaded. Many thanks
