I have marked the parameters that are sensitive to optimization. You can initially set ATR to 200 - 250, then the dependence on re-optimization will be less. Window and Alpha are quite stable over time, if Window is not less than 350-500. But if you want to trade frequently with Window less than 200 and Alpha less than 1, then re-optimization will be required.
Your broker's leverage margin matters.
The higher the leverage margin, the lower the "Risk Limit" parameter should be. In the examples given, the broker's leverage margin is 1:100.
For example, with a leverage of 1:1000, I recommend that you reduce the "Risk Limit" to 100 and regulate it separately with the TakeProfit parameter.
