Open Source Trading

Support the Mission

Hey, I'm SireMammat. I build rule-based Pine Script strategies and share them completely free — no courses, no subscriptions, no upsells.

Everything I publish is designed with one type of trader in mind: someone grinding prop firm evals, trying to pass with real discipline and real risk management, not luck.

My flagship script — the SireMammat Always-In + Chop Filter — took months of iteration, backtesting, and real-money observation to get right. It combines Al Brooks' Always-In EMA framework with an institutional-grade chop filter that stops you trading when the market hasn't picked a direction.

THE STRATEGY FOCUS

"Protect your eval account on the days that kill most traders — the slow, grinding, directionless sessions."

Want to say thanks?

I don't charge for any of my work. But if a script helped you pass your eval, land a funded account, or stop over-trading — you can support the project directly via Wise.
