Thank you GraHal for your suggestion. Have used the cursor details window and the Histogram Height is not above 0.00025 or below for the sell -0.00025.

And thank you Nicolas also. I have tried the integers of MACD[12, 26, 9] (close), instead of the formula MACD[37/3, 77/3, 9] (close). It did not change anything.

I rewrote the code. Mainly looking back the 5 candles.  indicator2, the MACD, is formulated to be the histogram height.

Changed the minimum height of the histogram to 10, which it almost never is in forex, to illustrate that indicator2 does not work.

The trades open whether the histogram height is 0.000001 or whatever.

How does the backtest have a result if the histogram height is never correct?

The attachment shows a trade opened by backtest with the MACD Line minus signal at 0.00016 shown in the cursor details window.

Any help or suggestions appreciated.

Thank you Vonasi, for your help. I have corrected the code. The MACD is the histogram height and that is what I now use.

But when I run the code, it still trades when the MACD line minus signal (9) is under the +or – 0.00025.

What is wrong with my code? Help me please.
