The indicator (plotted on the chart - image below) is free and works best on 30min & 1h time frames but can also be used on 5min time frame with correlation to support and resistance levels. Below is a brief description.

Works well with Bitcoin and other crypto assets. It utilizes modified MFI settings to create buy/sell signals. It also includes 20, 55, 100 EMAs with additional rules toggle to plot only buy/sell signals when EMAs are in bullish or bearish alignment. That setting allows for the signals to be more accurate by excluding most false ones. In addition we also included Bollinger bands for easier and safer position exits at the upper or lower band. This technique is meant for scalping and quick in and out trades. Install/test and read more detailed description on TV here.
