The StrongBars indicator allows you to highlight candles that are above a threshold of their average volume, delta, or range, or any combination of those conditions.
Lookback period: how many bars back to determine the average value.
Proximity to average: the threshold for highlighting bars (if 1, bars will be colored if current value is above 1x the average, etc).
You can use support/ resistance markers which plots a dot or a zone at the high or low of the candle.
If all three filters are on, bars will be highlighted if they are above average volume, delta, and range, making them very strong bars.
