HalfTrend — Trend Line, ATR Channel & Buy/Sell Signals with Smart Alerts
**HalfTrend turns noisy price action into one clear question: are we in an uptrend or a downtrend?**
It draws a single stepped trend line that flips color when the market genuinely changes direction — blue for uptrend, red for downtrend — surrounded by an ATR channel that shows you exactly where volatility says your stop belongs. No lagging MA crossovers, no cluttered chart: one line, one channel, one arrow when it matters.
---
## How it works
HalfTrend tracks two adaptive levels: the **highest of the lows** while trending up, and the **lowest of the highs** while trending down. The trend only flips when BOTH conditions are met:
1. The moving average of lows/highs crosses the opposite extreme level, **and**
2. Price closes beyond the previous bar's high/low.
This double condition is what filters out the fake breakouts that kill single-MA systems. The ATR(100)-based channel around the line adapts stop distance to current volatility automatically.

## Features
- ✅ **Non-repainting after bar close** — once the signal bar closes, the arrow is fixed forever
- ✅ **Clear Buy/Sell arrows + text labels** at the exact flip bar
- ✅ **ATR channel** (dotted lines + colored ribbon) for stop placement and volatility context
- ✅ **5 notification modes**: MT5 Alert, MT5 mobile push, Email, Telegram message, Telegram with chart screenshot
- ✅ **"Alert on bar close" mode** — get notified only on confirmed, non-repainting signals
- ✅ **Lightweight** — incremental calculation, object-based arrows, no buffer bloat; friendly to EAs reading its buffers
- ✅ **EA-ready** — trend state exposed in a buffer (0 = up, 1 = down) for easy `iCustom` integration
- ✅ Works on **any symbol and any timeframe**

## How to trade / read the signals
| What you see | What it means |
|---|---|
| **Blue line below price** | Uptrend active — look for longs only |
| **Red line above price** | Downtrend active — look for shorts only |
| **Blue arrow up + "Buy" label** | Trend just flipped up — long entry signal |
| **Red arrow down + "Sell" label** | Trend just flipped down — short entry signal |
| **Dotted ATR channel** | Volatility envelope — natural stop-loss zone |
| Price pulls back to the line but line keeps color | Trend intact — pullback, not reversal |
**Long playbook:**
1. Wait for the buy arrow **and let the signal bar close** (or use "Alert on bar close" mode)
2. Enter at the open of the next bar
3. Stop-loss: below the lower ATR channel line, or 3×ATR(14) for swing trades
4. Exit: on the opposite (sell) arrow — let the trend run instead of using a fixed take-profit
**Short playbook:** mirror the above on a red flip.
**Signals to skip:**
- Flips during tight sideways ranges — check ADX(14): below ~25, skip the signal (this single filter removed most losing trades in our 8-year backtests)
- Arrows that appear mid-bar and vanish — an arrow is only final when its bar closes
- Signals against the higher-timeframe HalfTrend color, and entries minutes before major news
**Recommended starting point (from 8 years of backtesting):** H4 timeframe, Amplitude 2, entries on confirmed flips with ADX(14) ≥ 25, stop 3×ATR, exit on opposite flip. Scalping on M5–M15 with raw signals is NOT recommended — this is a trend tool, let it breathe.

## Notes
- The arrow can appear intrabar and disappear if price reverses before the bar closes — this is the live nature of any trend indicator. Keep "Alert only on closed bar" enabled for fully confirmed signals.
- For automated trading, read buffer 9 via `iCustom`: value 0 = uptrend, 1 = downtrend. A flip between two closed bars is the entry signal.
