Hello trying to understand the difference between "Bid Ask Volume Ratio" and "Up/Down Volume Ratio" that is based on Ask/Bid Volume. From the documentation Bid Ask Volume Ratio and Up/Down Volume Ratio , it appears they use the same formula, except for conditions of V(ask)+V(Bid) around 0 values. The other difference I noticed is in terms of the EMA calculation for t <n , between the two.For t >=n, they appear to be the same. Can you confirm if my understanding is right? I can see the calculations used, but in layman's terms, how would you characterize the difference between them? It looks the same to me, for the typical conditions and yet I see the Bid/Ask volume ratio , to be a bit more sensitive, for the same moving average length and moving average type(exponential). The up/down volume ratio(ask/Bid volume) seems to be a bit more smoothed out. No issues either way, just trying to understand what/why the difference is.. Thanks |

The "Bid Ask Volume Ratio" and "Up/Down Volume Ratio" will give the exact same results if they have the same parameters and the "Up/Down Volume Ratio" is has the "Calculated Based On" set to "Ask/Bid Volume". If you are seeing differences, then there must be something different in the Length or Moving Average between the two studies.

Never mind, my bad..I had a moving avg on top of up/down volume ratio, which I thought I had disabled, but apparently it was still on and the base up/down ratio had it(VR) hidden, causing the difference in sensitivity. Thanks! Date Time Of Last Edit: 2024-12-03 20:53:15
