Live Monitoring

Read these first

1. 01Designing a Strategy Kill Switch

   A kill switch only works if its trigger is a number decided in advance, checked automatically, not a judgment call made by someone watching a P&L line drop in real time.

2. 02A Monitoring Stack for Live Strategies

   A backtest is a photograph of history. A monitoring stack is the live camera that tells you, today, whether the strategy behind it is still doing what the photograph promised, before the drawdown does the telling for you.

3. 03Decomposing Live Slippage

   The gap between the price you saw and the price you got is one number on a report, but it is made of several different mistakes stacked together. Slippage attribution splits it back into the pieces so you know which one to fix.

4. 04Monitoring Signal Decay in Production

   Every signal has a shelf life, and the backtest that proved it worked cannot tell you when that life has ended. Decay monitoring is the ongoing measurement that catches a signal going stale before the drawdown announces it.
