This is a tool, shows the volume variation % strength related to the X past candles.
The current candle is shown in real time, until candle closes.
The visualization of the candle time to close is a thin line, that is 100% for all past candles and slowly goes up for the current candle.
Best with an example:
with a 4h candle, 1 hour has wasted already. This is 25% of all the candle time. So, if volume is also at 25% of the last candles traded, we can expect(yeah, you wish) that by candle close, around 100% of the last volumes average will be traded.
Or two:
in a 4h candle, we're at 10mins., around 8% of total candle time. If volume traded is already at 57% of average past volumes, something big is going on.
Note 1: in the indicator's "Format" pop-up there is a "candle minutes" field, it MUST match the chart timeframe in minutes (ex: 4h=240min)
Note 2: the back volume function check can be switched between the methods "highest value" or "average", in the Format->inputs
Note 3: when a new candle opens, it will go craaayeeezeee!!, because the extreme small values introduce a lot of rounding errors. just let it go, it calms it self after ~0.5% of candle time has passed.
There are more examples and details in the early version of this indicator, check my published scripts.
