Determining trends and reversals are the keys to trading, yet very difficult. Parabolic SAR is hard to trade during choppy price action. SuperTrend is a bit late in determining changes of trend and not great and exit signals.
So WonderTrend is a bit of both, a more stubborn PSAR, also a faster SuperTrend. The green is up, red is down, and yellow is caution helps traders read the chart patterns to enter and exit.
Enjoy!
