Please, answer the questions.

1. Why do you use the Fractal's value on the 2nd closed bar? It's not formed yet. I think you should use the 3rd closed bar value:

   CopyBuffer(fracDef,LOWER_LINE,3,1,fracDownArray);

2. Why do you call them trading systems? They don't make trades. Only comments on the chart.

Current candle is 0, the previous one is 1, and the third is 2 not 3.

Trading systems as they programmed based on systematic and logical steps to help you to trade even if they are comments, You can add sending orders if you tested them and found them useful for you.

Current candle is 0, the previous one is 1, and the third is 2 not 3.

The 3rd closed candle is 3. The current candle (0) is not closed yet, and using it could give many false entries, especially when it has recently opened.
