Need to find largest volume on down days in last "n" days

[erukumk]

I am looking to find largest volume on a down day in lookback period to use in filter condition. Below is the code i have written, please help.

// Calculating highest down volume day.
LookBack = Param( "LookBack", 10, 9, 15, 1 ); // Look back periods

DownVolume = 0;

for( i = 0; i <= LookBack; i++ )
{
    if( Open[i] > Close[i])
    {
        DownVolume[i] = Volume[i];
    }
}

// Filter for trend conditions
FC1 = C > MA( C, 10 ) AND Close > OPEN;
FC2 = MA( V, 10 ) > 100000;
FC3 = Volume > HHV(DownVolume, LookBack);

Filter = FC1 AND FC2 AND FC3;

AddColumn( Close, "Close", 1.2 );

@erukumk something like this

Finding the highest volume on green and red candles

@richyrich I am not sure I understood what you are looking for. The highest volume for "Green candles" in last 25 bars (and same for "Red")? But later you mention the SUM function, so are you looking to add up the Volume of Green and Red? Below are some attempts (I use 5 bars as it was easier for debugging, so you can change it to whatever you like). GreenCandle = Close > Open; RedCandle = Close < Open; // What color do you want to call the candle if Close=Open ? RedVolume = IIf(RedCandle, …
