%%They are definately different in the same timeframe. Backtesting them in some way, may yield vastly different results as well, or not.
That you believe they are the same/very similar is just an unproven assumption of mind. Such assumptions can block progress because you keep beliefs not based on verified facts. That your charting package hinders you to explore all options, is also a limitation.
I don't mind, just stating the way I see it from own experience.
The way i use volume, its not that much different @ all [50 days or 200dma volume] BUT a severe limitation on 200 dma= is you have to get 200/201 days of data to get only one /two volume marks. IF all i could get was a 200 dma on volume i go to IBD[investors.com] they auto draw 50 dma on volume........ Or simply draw 50 or 60 days trend lines on volume myself.
A 200 day [ or 52 weeks] huge volume decline or volume spike may not mean much @ all;
QQQ has done both, since inception, no problem@ all, but if it ever averages below 1 million per day , i may get another benchmark LOL
