How to Add a Regime Filter to Any Crypto Portfolio Strategy
You don't need to rebuild your trading strategy. You just need to add one filter on top: the market regime. Here's how to do it in 10 minutes with any existing setup.
The Concept
A regime filter doesn't change WHAT you trade — it changes HOW MUCH. Think of it as a volume knob:
- Bull regime: Volume at 100%
- Chop regime: Volume at 40%
- Bear regime: Volume at 10%
Your existing entry/exit signals stay exactly the same. The regime filter just scales your position size.
Implementation (Any Language)
Python
``python
import requests
def get_regime_multiplier():
data = requests.get("https://getregime.com/api/v1/market/regime").json()
scale = {"bull": 1.0, "chop": 0.4, "bear": 0.1}
return scale.get(data["regime"], 0.5)
In your existing strategy:
position_size = base_position * get_regime_multiplier()
`
JavaScript/TypeScript
`typescript
import { CseClient } from 'getregime';
const client = new CseClient();
async function getRegimeMultiplier() {
const { regime } = await client.getRegime();
return { bull: 1.0, chop: 0.4, bear: 0.1 }[regime] ?? 0.5;
}
`
cURL (for scripts)
`bash
REGIME=$(curl -s https://getregime.com/api/v1/market/regime | jq -r .regime)
case $REGIME in
bull) MULT=1.0 ;;
chop) MULT=0.4 ;;
bear) MULT=0.1 ;;
esac
`
Results From Backtesting
Adding a regime filter to SMA 50/200 crossover (302K candles):
| Asset | Without Filter | With Regime Filter | Improvement |
|---|---|---|---|
| BTC | +41% | +41% (less drawdown) | -40% max DD |
| ETH | +41% | +166% | +305% |
| SOL | +312% | +586% | +88% |
The filter's biggest win isn't better returns — it's avoiding the worst drawdowns.
When NOT to Use a Regime Filter
- High-frequency strategies (< 1 min): Regime changes too slowly to matter
- Market-making: You profit from both sides regardless of regime
- Arbitrage: Edge is regime-independent
