This script adds the 52 weeks (one year) high/low to the chart but it wouldn't update the value on the current trading day, so that it would remain at the same level for the whole trading day. It can come really handy for day trading the day of the 52 weeks high/low breakout/breakdown.
Just a simple script that tweaks the original Volume one.
The purpose is creating a threshold which we'll use to put an alert on. This way, we can be notified whether Volume pumps.
Useful for spotting breakouts, breakdowns and pumps.
Threshold is simply a coeff * ma(volume,period). Coeff is editable as well.
Hope this helps!
