Thanks for sharing. I think DD of 3.41% sounds pretty awesome and considered to be quite safe for now. Your profits of 9.547 in 13 days which is roughly close to a two weeks period. If you do an estimate calculation of your monthly profits, I think it would be quite close to 6%-7% or so which does not sound that great to many, but yet it is still good enough for some people. Perhaps the only possible major risk that I see is the 1.5 multiplier value which is using the martingale strategy. As we all know that martingale strategy could be very profitable but at the same time it could be very risky too especially when the market turns extremely volatile at certain times. However for your strategy, because you are using a much bigger step of 200 and also you have limited the max trade (each side) to the value of 3 only, it is obvious to me that you have significantly reduced the risks which is good and considered to be much safer for your account.
Therefore, I think that your settings should be quite safe for now and if I'm not mistaken, I think it could help to keep you safe for a much longer period. Just that this strategy might not able to give you any monthly profits of bigger than 10% or more. Having said so, if you are happy with that smaller percentage of profits earned per month, then I think this strategy would suits you very well then.
Wish you all the best with your strategy. Keep up the good work, be safe and stay safe as always, take good care and God bless
