I think the current logic of adding a 0.08 commission to the foot size is wrong.

It was puzzling that at the same distance from TVH to the stop, the indicator shows 2.25%, and finance - 2.33%. If you put a commission at a stop, this should be reflected correctly on the chart (at least the stop line should be lower on the chart) and influence the position size when trading from risk. It's all connected.

In fact, just adding a comb to my foot is the wrong decision. On the screenshots, for example, the commission in my calculator affects exactly the size of the position and the amount of risk. In your case, it should be like this: The risk is set at $15, stop is 2.25%, and the GRAPH SHOWS 2.25% and the risk is 14.80 (including the commission) AND REDUCE THE POSITION SIZE BY THE COMMISSION. And it turns out that your risk is increasing. Of course, these are trifles, but the logic is not entirely correct.
