DislikedI openly admit I do not understand code, so pardon me for my ignorance.
I can see how this suggestion to change "null" to "symbol" might relate to which currency pair the ATR refers to, but what is the meaning of changing the "0" to "60"? Does the "60" specify a timeframe, such as 60 minutes regardless of the timeframe of the chart the EA is loaded on? And if so, does the 0" refer to the timeframe of the chart the EA is loaded on?Ignored
"null" would only use the currency pair it is attached to whereas "symbol" takes all the currency pairs the EA is trading.
The 60 would specify a 60 minute timeframe, so as Steve mentioned earlier I would leave this to "0", so the EA takes the TimeFrame of the chart it is attached to.
