Hi guys, since quite a while I am unable to find out how to set the alert condition i.e. for the Bill Williams Fractal study so that I get an alert once the "tringle" is placed. Can you pls. help me out? Cheers Pete |

All you need to do is the following for the Alert condition: =ID1.SG1 Where ID1 is the ID of the Bill Williams Fractal study and SG1 is the Buy Subgraph. This means to alert when the Buy subgraph is non-zero. You would change this to SG2 for the Sell signal. If you want to check both, then you would need to use an OR like this: =OR(ID1.SG1, ID1.SG2) Refer to the information for alerts here: Study/Chart Alerts And Scanning For the most reliable, advanced, and zero cost futures order routing, use the Teton service: Sierra Chart Teton Futures Order Routing |

Thanks John - tried exactly this (see settings attached) but it doesn't work. Any further idea what to do?

Sorry, it was pointed out that the Bill Williams Fractal actually does not check the current bar, rather it looks at the previous 4 bars. Therefore, you would have to put the following formula to alert then the signal occurs: =OR(ID10.SG1[-1], ID10.SG2[-1], ID10.SG1[-2], ID10.SG2[-2], ID10.SG1[-3], ID10.SG2[-3], ID10.SG1[-4], ID10.SG2[-4]) For the most reliable, advanced, and zero cost futures order routing, use the Teton service: Sierra Chart Teton Futures Order Routing |

Thank you, the alert formula works fine now but another thing came to my attention: there are by far more short than long signals. 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). When I compare to other platforms i.e. TradingView they show many more BW Fractal signals. Is this a mistake from your side or is there an explanation?

We will look into this and respond. Most likely this is what the original implementation from Bill Williams stated, but we will verify and let you know.

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.

The study Bill Williams Fractal Signals has been modified using the logic in the following documentation. Bill Williams Fractal Signals The changes will take effect in the next release. |
