A good-looking backtest is easy to manufacture by accident. The platform treats that as a starting point, then checks out-of-sample behaviour, parameter stability, market regimes, fees and slippage.

Weak ideas stop there. Survivors move forward with their limitations written down instead of hidden behind one headline return.

Vectorized research makes broad experiments cheap. Walk-forward validation tests whether an edge transfers beyond the data that found it. The same strategy then runs against real exchange data in paper mode.

That last step catches the operational failures a notebook cannot: stale feeds, reconnects, order state, position sizing and what happens after a process restarts.

I would rather combine simple strategies that behave differently than search forever for one perfect system. Monitoring keeps the evidence current and makes it possible to retire an edge when the market changes.
