⚙️ WHEN SHOULD YOU CHANGE A TRADING STRATEGY?
One of the easiest ways to destroy a systematic trading strategy is to keep “improving” it.
Three losses in a row? Add a filter.
A bad month? Change the entry.
Missed a large move? Adjust the parameters.
The backtest may improve — but eventually the strategy you originally tested no longer exists.
This is one of the biggest traps in algorithmic trading: reacting to recent results instead of evidence.
Before changing one of my systems, I want to know whether something meaningful has actually changed.
- Has execution deteriorated?
- Has market behavior moved outside the conditions the strategy was designed for?
- Is live performance becoming statistically inconsistent with testing?
- Is there enough new data to question the edge itself?
If not, sometimes the most difficult decision is also the correct one: do nothing.
Every meaningful modification effectively creates a new version of the strategy — and that version needs to be tested again.
There is a big difference between improving a system and chasing its last few trades.
Good systematic trading requires knowing when to optimize.
It also requires knowing when to leave the strategy alone.
