100% volume change


#1

I often see volume changes of 99 or even a hundred percent written to the configs. For example.

# Volume change (720): -98.24%
# Volume change (1440): -99.11%

Math has never been my strong point but surely a 100% fall in volume means it has to be 0 after the fall whatever the volume was to start with? But the coin still has a volume of around 70. Even a 98% fall means it started at 3500 before falling 98%. But Bittrex hasn’t had coins above 1000 or so for weeks. And the coin in question hasn’t been near that high …

So what am I missing?

A 0 volume is possible. This volume looks at the volume per 5 minute candle, not 24 hour volume.

It’s not ideal as the volume per candle can change drastically and the percentage change you see is the change from the candle MinutesToMeasuretrend ago and the current candle.

In Feeder 1.7, there is the option of using VWMA which should be a more accurate representation of volume change.

Ah! That makes a bit more sense I think. Thanks.

I assume the volume written to the configs is referring to the ‘same’ candle as the volume change percentage? So I still don’t quite see how the volume can still be 70 after falling 99%. That would still mean the volume was several thousand even for only that candle? But as I said math isn’t my strong point … :wink:

Looking forward to Feeder 1.7.

That is a good point. I should probably remove this from the comments actually too as this volume measure doesn’t really give any valuable information.


#5

Please don’t remove it. It’s still useful I think - just not as useful as I thought it was! But if you could write the VWMA instead that would perhaps be better. There can never be too much info written to the comments IMO. It’s just a question of understanding what it’s telling me …

Sure, VWMA is written to the comments in 1.7.
