Summary
The post is a general inquiry from a novice algorithmic trader asking experienced practitioners how they validate a trading strategy's "edge" before deploying it with real capital.
The author is concerned about common pitfalls like overfitting, slippage, and market regime changes that can cause a strategy to fail in live trading despite a successful backtest.
Quality assessment: This is a general question seeking advice, not investment due diligence (DD) or speculation on a specific asset. It is noise from a trade signal perspective.

Hi everyone,I’ve been exploring algorithmic trading strategies recently and had a question for the more experienced people here.A lot of strategies look great in backtests, but I often hear that many of them fail once they go live because of things like overfitting, slippage, or market changes.
I’m curious how do you personally validate a strategy before trusting it with real money?So do you usually paper trade it for a while first, or do you mostly rely on backtesting results and certain metrics?
Just trying to learn how others approach this.
