Hello

I am trying to create a simple strategy based on Bill Williams' fractal indicator. I have attached my work to date. My strategy aims to do the following:

1. Filter for instrument and period
2. Look at the five most recent candles to determine if a new upper fractal formed.
3. If a new upper fractal is formed:
a)Assign the price of the upper fractal to the variable "Fractal_up"
b)Cancel any unfilled pending orders based on previous upper fractals
c)Set a new pending order based on the new upper fractal

My questions:
1. The strategy appears to be working, but I get a series of error messages that relate (I think) to the cancelled pending orders. What is causing these errors, and how can I fix them?
2. In determining the price of the most recent upper fractal, I am looking at the last five candles individually using the "Get Historical Candle" block. I am looking at the current candle (which I call candle zero given that its shift = 0) and candles shifted 1, 2, 3 and 4 time periods back in history. If a new fractal forms in the last five candles, it would be based on the middle candle (that is, the candle shifted 2 time periods back), which I have called candleshift_2. Can anyone comment as to whether my logic is correct here, or suggest a better approach?

Thanks in advance for your help, and thanks for providing such a great tool. It opens up a whole world of possibilities to non-programmers such as myself.

Greetings!

As far as I understand the FRACTALS indicator (please correct me if I am wrong!) you need to setup 5 candles or any other odd number. After that determine if the candle in the middle has extrema (high/low) in reference to the other candles next to it.

You can also consider using the attached strategy for Fractals.

Anyway: A tiny little mistake I have found in your strategy...: Like you said, it was related to the close of the PO.
