This is an updated version of my base algorithm "BTC Precognition". I've managed to remove some lag, while at the same time smoothing the curve (blue).
All you need to know about it is on the chart's legend. The arrows just correspond to the bottoms/tops of the blue signal curve (marked with green/red circles). However, predicting turning points is difficult and I'm still working on that. So for now, the signals are offset by 1 candle into the past. This means that all of your trades will be 1 candle late, unless you trade intrabar using your own intuition. As a help, I've also included the first derivative (black curve) that will tell you the slope of the blue curve. Remember, when the curve is about to turn, the slope becomes zero. However, you can anticipate this by looking at the slope's direction and guessing when it will cross the zero line.
This is still all work in progress, so invite-only.
Added a probability score that is based on looping through several dozen smoothing periods to identify the most frequent bottom/top areas.
In order not to lose sensitivity, smaller smoothing periods are exponentially more weighted.
The probability score (in %) can be read from the bar height. The arrow-only version of this script also allows to set thresholds to fit your own preferences.
