Hey All!! How to consider drawdown as a factor in selecting the Algos?

I recently backtested a strategy in Nifty Options Intraday for the last one year.

On the total capital needed, the max DD was 20%, backtest yielded 75% returns after considering charges and 0.5% slippage.

So I intend to forward test it for a month and deploy.

So how should my capital be allocated here? Should I expect more drawdown and how to prepare for that.

Is 0.5% Slippage is enough for Nifty Weekly Options, mostly ATM & OTM? Should I consider more?

Looking forward for the valuable inputs from the community. Thanks!
