If I want to creat a pcf combining rsi, with relative volume of the particular tick, compared to mean volume, how would I do it?..Thanks.

I do not know the settings of the RSI, if the RSI is the plain RSI or the RSI - Wilder's indicator, the period you wish to use to calculate mean volume or what specifically is of interest about RSI and relative volume.

How specifically do you want to combine RSI and relative volume? What do you want the PCF to do?

I wanted to figure a way to "weight" a 14 period RSI with the relative volume(compared to the average 5 minute volume) in a 5 minute time period. I think an indicator combining volume and rsi would be helpful..Thanks!

Also, you have mentioned that for shorter time frames, the plain rsi, not wilder's, is better.

So you just want to use Simple Volume Weighted Moving Averages when calculate the RSI instead of the Simple Moving Averages used in the plain RSI or the Wilder's Smoothing used in the RSI - Wilder's? If so, please try the following for a 14-Period version:

100 * ((C > C1) * (C1 - C) * V + (C1 > C2) * (C2 - C1) * V1 + (C2 > C3) * (C3 - C2) * V2 + (C3 > C4) * (C4 - C3) * V3 + (C4 > C5) * (C5 - C4) * V4 + (C5 > C6) * (C6 - C5) * V5 + (C6 > C7) * (C7 - C6) * V6 + (C7 > C8) * (C8 - C7) * V7 + (C8 > C9) * (C9 - C8) * V8 + (C9 > C10) * (C10 - C9) * V9 + (C10 > C11) * (C11 - C10) * V10 + (C11 > C12) * (C12 - C11) * V11 + (C12 > C13) * (C13 - C12) * V12 + (C13 > C14) * (C14 - C13) * V13) / (ABS(C0 - C1) * V + ABS(C1 - C2) * V1 + ABS(C2 - C3) * V2 + ABS(C3 - C4) * V3 + ABS(C4 - C5) * V4 + ABS(C5 - C6) * V5 + ABS(C6 - C7) * V6 + ABS(C7 - C8) * V7 + ABS(C8 - C9) * V8 + ABS(C9 - C10) * V9 + ABS(C10 - C11) * V10 + ABS(C11 - C12) * V11 + ABS(C12 - C13) * V12 + ABS(C13 - C14) * V13 + .0000001)

ok..thnks!

You're welcome.
