Hello: I am trying to create a couple of Explorations for the following formula: ADJUSTABLE TRADING BANDS by TUSHAR CHANDE {Upper Band} Prd1a:=Input("ATR Period",5,20,5); Prd2a:=Input("Period for Highest High Value",5,20,10); (HHV(LLV(L,Prd1a)+ATR(Prd1a),Prd2a)); {Lower Band} Prd2b:=Input("Period for Lowest Low Value",5,20,10); (LLV(HHV(H,Prd1a)-ATR(Prd1a),Prd2b)); One exploration would return stocks that have moved from below the lower band to above the lower band. Possible start of uptrend. The other exploration would return stocks that have moved from below the upper band to above the upper band. Possible continuation of uptrend. I have been able to create an Expert Advisor symbol that shows when these situations occur but get erroneous results when I try and run the Explorer using the same criteria. The other solution I have tried but am unable to do is create two separate indicators. One for the lower band and one for the upper band. The ATR period I am using is 6 with a HHV and LLV look back period of 18. Thanks for any help, Dave

Hi Roy Thank you for the reply. I did not have the minimum number of records set but I did increase the number of records to load. Seems to have done the trick. Thanks again Dave

Hi Johnathan Loading way more bars than are needed could slow execution times excessively and possibly isn't the best option. A general setting of somewhere between 200 to 500 bars would probably give sufficient accuracy in most situations. Obviously code with a 200 day EMA would be more accurate with say 1000 bars. Many MS functions force about 1.3 times the highest Periods parameter number of bars to load with the Minimum Records setting, and they work fine like that. What many (usually newer) users don't understand is that exponential MAs use ALL available data to generate a result, not just the bare minimun number as set by the Periods parameter. You'll know this but Dave and others might not - the explorer calculates code results in exactly the same ways as a chart, and given the same amount of data it will come up with exactly the same result. All that's different is that only the last-bar value is reported by an exploration, and the calculation result isn't as accessable for other bars as it is with a chart. Roy
