But if we change parameter's value, that's mean the backtest result is wrong compared to our current strategy ?

Old backtests yes, but you can run a new one (with your new parameters) in a second. I've just added some docs to the backtesting documentation that might be of interest. See here: https://gekko.wizb.it/docs/features/backtesting.html
