Bitcoin will not be down forever.
I know, a lot of people are panicking.
Bit to be honest, when you can not hold for a few months, why have you invested?
And when you are a trader like me, why the fu*k you are complaining ?
This is just a great short.
The result is a high-fidelity forensic log explaining why each of the 972 strategies passed or failed. This enables systemic validation of model behavior across all market regimes, isolating silent failures from intended patience.
Instrumenting the simulation engine to log the specific rejection reason for every signal is the solution. This exposes internal state metrics for each strategy, mirroring the observability of production systems within a sandboxed environment.
This yields a complete decision log, not just a trade history. Analysis reveals the true ratio: for every executed trade, hundreds of signals are evaluated and filtered. This data becomes a direct input for systematic filter calibration and performance tuning.
Instrumenting the signal engine to write every evaluation to a dedicated event pipeline solves this. Each potential entry should log its raw state, the filters applied, and a specific rejection reason (e.g., `filter_blocked`, `insufficient_data`, `adx_below_threshold`).
The outcome: Full historical drill-down capability is achieved for analytics. The live production engine remains untouched, with zero new code paths and zero added risk to its core operation. Analysis is decoupled from execution.
The solution: A 1:1 clone of the production engine is created for offline analysis. This clone is modified to add the required timestamp tracking. A parity test confirms its PnL output is bit-for-bit identical to the live engine across all exit modes.
