Why risk control comes before execution

In an automated trading system, where risk control lives determines whether it works when it matters. Our approach: risk is an independent gate between signal and execution.

What happens when risk lives inside the strategy?

When risk is just a parameter inside a strategy, it gets tuned and optimized along with the strategy. Too often, limits get loosened to make a backtest look better, or a new strategy ships without the same constraints.

Three principles of independent risk control

1. Risk rules are managed separately; a strategy can't loosen its own limits.
2. Every signal must pass each check; if any check fails, it doesn't execute.
3. Blocked signals are logged with a reason for later review.

Common risk rules

• Position and exposure limits: cap single positions and total exposure.
• Stop-losses: define acceptable loss in advance.
• Cooldowns: avoid rapid-fire entries and exits.
• Abnormal-market pauses: halt execution on violent price jumps or data anomalies.

Often the most important thing a system can do is nothing

A good risk system looks idle most of the time. But when markets move violently, data breaks or a strategy stops working, it's the last line of defense that keeps losses contained.
