# Half Trend ### Overview **Half-Trend** is a **trend-following, step-style baseline** with an **ATR-based channel**. It climbs in uptrends using the **highest recent lows** and falls in downtrends using the **lowest recent highs**, flipping only when **price + smoothed extremes** confirm the change. You get a clean staircase baseline and symmetrical bands to trade **breakouts, pullbacks, or trend filters**.
### Interpretation * **Trend filter**: trade **with** the staircase direction; avoid counter-trend entries unless mean-reverting by design. * **Breakout entries**: a close **above Upper band** in a rising baseline often signals **momentum continuation**; below Lower band in a falling baseline suggests **downside continuation**. * **Pullback entries**: in an uptrend, **touch/hold above the baseline or lower band** can be an entry with tighter invalidation; inverse for shorts. * **Volatility awareness**: wider ATR ⇒ **wider bands** mean fewer false signals but slower reactions. ## Indicator Triggers:
### Cross Band

We want to place a long signal when price cross up the upper band.

### Touch Band
We want to place a long signal when price touch down lower band

We want to place a long signal when price touch down lower band

### Band Distance

We want to place a long signal when half trend band is between 0.5 and 2% under the price

### Trend Swap

We want to place a long signal when half trend swaps bullish.

### Trend Status

We want to place a long signal when half trend status is bullish.

### Strategy Ideas * **Trend-Follow:**\ \&#xNAN;*Enter long* on **close above Upper band** when baseline is stepping up; stoploss on **close below Baseline**. * **Pullback-Buy:**\ \&#xNAN;*Enter long* on **touch down of Baseline/Lower band** while trend is up, with stop under Lower band; symmetric for shorts. ### **Runbot Trading Tips** * **Optimization:** Let the AI Agent Optimizer tune **Amplitude** and **Deviation** across regimes; evaluate **APR vs. max DD** trade-off. * **Non-repainting:** Baseline steps only **forward**; flips require dual confirmation (SMA + price vs prior high/low).
Remember, no single indicator should be used in isolation. Always consider the broader market context and employ sound risk management practices in your trading. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
