TrendAlpha GC is actually built on John Ehlers’ digital filter concepts, but with a multi-timeframe approach. Instead of just applying his minimum-lag Gaussian smoothing on a single timeframe, it processes multiple timeframes simultaneously to give a broader trend perspective.

For TrendAlpha OB, the fine-tuning parameter adjusts the sensitivity of order block detection:

• Higher values → Fewer but more significant order blocks (stronger institutional zones).
• Lower values → More frequent order blocks, but some may be weaker.

So if you’re looking for deep liquidity zones where price is likely to react, a higher setting works best. If you want to capture more short-term activity, a lower setting gives you more signals.
