Order flow

Hi! I need an experience developer with order flow, volume delta, and futures scalping, and I wanted to ask you a few questions.

Have you personally developed and tested fast-paced strategies for Gold Futures (GC), particularly those that enter during short-term price impulses and scale into positions as momentum builds?

From your experience, what indicators or signals help you determine whether an impulse has enough strength to continue or is likely losing momentum? Do you mainly rely on executed trades and volume delta, order book changes, or price action?

Also, have you seen these types of strategies remain profitable after accounting for realistic commissions and slippage?

I'd appreciate a general example from your experience. No need to share any proprietary formulas or code.

Thanks!
