Multi timeframe, minute and range bars

[no111]

Short question: Is this a correct way to backtest? (Because of the lower timeframe)
I run this strategy on a range 4 chart.

Add(PeriodType.Range,10);//index1
Add(PeriodType.Minute,15);//index2
//so range 4 = index0 

if (BarsInProgress == 0)    
    {

    if(
RSI(BarsArray[0],14, 1)[0] < 25
&& Closes[0][0] > EMA(BarsArray[0],20)[0]
&& Closes[1][0] > EMA(BarsArray[1],20)[0]
&& Closes[2][0] > EMA(BarsArray[2],20)[0]
)

            {
                EnterLongLimit(DefaultQuantity, Closes[0][0], "LONG");
                
            }

                
                )

Hello no111,

Yes, looks good if your goal is to evaluate conditions on multiple intervals.
