OPEN-SOURCE SCRIPT
已更新 Volume Price ROC Tracker and Shadow Candles
When price goes up on negative volume, then market is telling there is doubts in investors mind.
The SPX upside recent month was a on. Lower volume so, the rally in my view will not last. Read my articles on current market.
This very simple scripts shows if price drop or gain was on a upside volume or down side. It is a visual track on the candle reflecting the volume ROC overlapped as a price movement on the actual candle. So don't mistake it with a moving average. Red means volume was down even if price has gone up. Basically if a price goes up on a increase ROC volume then you can trust it. Otherwise it is likely that it won't last.
If you can improve on this idea, it would be great. I think there is not enough volume related scripts that diggs a bit deeper to describe the market behaviour in the future. After all all technical analysis are supposed to tell us about future price not just how it was in the past.
