This indicator looks for confluence among three indicators ( RSI , Stochastic , and MACD ), a strategy popularized by Markus Heitkoetter in his book, “The PowerX Strategy: How to Trade Stocks and Options in Only 15 Minutes a Day”, and expands it to look for agreement on up to four symbols.

Each indicator is configurable in the settings, as well as the ability to choose which of the indicators are used.

Default Logic
Green Candles
RSI > 50
Stochastic > 50
MACD Histogram > 0

Red Candles
RSI < 50
Stochastic < 50
MACD Histogram
