The upper chart is the Bitcoin-USD price. The BUY and SELL signals are shown with "red" and "green" rectangles respectively.
Since the crash of 2018, this signal has had significant results.
The lower chart is SixSilverSpoons' Stable Coin chart. The higher band of the cone is the SELL signal area and the lower band of the cone is the BUY signal area. When the SSS chart enters these areas, the SELL or BUY signal triggers.
It is a very easy chart to use. I just need to make it prettier maybe by putting the formula into an indicator.
If you have any comments about this chart, please let me know.
