Regarding Post #5:


Checking the SC documentation it looks that different criteria are used to determine long vs. short signals and the long criteria are much tougher (see attached screenshot).

You are correct. The conditions for Buy Signals and Sell Signals are asymmetric. I did not code this study, but I did document and test it. At the time, I did not have the primary source material from Bill Williams handy, and I did not know what the correct inequalities should be, so I did not recommend a change. Since then, I have obtained a copy of Williams' book New Trading Dimensions, and I have learned that the correct logic should be as follows.

Up Fractal (Buy Signal):
* H(t) > H(t - 1)
* H(t) > H(t - 2)
* H(t) > H(t + 1)
* H(t) > H (t + 2)

Down Fractal (Sell Signal):
* L(t) < L(t - 1)
* L(t) < L(t - 2)
* L(t) < L(t + 1)
* L(t) < L(t + 2)

I have recommended this change to Sierra Chart Engineering and will implement it if directed to.
