Trend Line Alerts
An indicator that monitors hand-drawn trend lines on price charts and fires multi-channel alerts — and optionally places trades — when price crosses a trend line.
What It Does
You draw trend lines on your chart. The indicator watches them. When price crosses a line, it:
- Shows a popup on the chart with the crossover details
- Plays a sound notification
- Sends an email (optional)
- Sends a Telegram message via bot (optional)
- Places a trade (optional — market, limit, stop, or stop-limit order)
Alert System
- Trend line crossover detection — fires on every tick when price crosses above or below a tracked trend line
- Rich messages — includes trend line price, current bid, distance in pips, instrument, and time-frame
- Rate limiting — configurable cool down per trend line prevents duplicate alerts
- Alert history — last 500 alerts stored and viewable in the Trade Panel
- Multi-channel delivery — popup, sound, email, and Telegram simultaneously
Trading System
When trading is enabled, a crossover event can also place a trade:
- All C-Trader order types — market, buy/sell limit, buy/sell stop, buy/sell stop-limit
- Auto direction — price crosses below → sell, crosses above → buy (or set manually per line)
- Stop loss and take profit — specified in pips, converted to price levels automatically
- Two volume modes — fixed lots or risk-based (% of account balance)
- Per-trend line overrides — each trend line can have its own trade settings (direction, volume, SL / TP, order type)
- Trade management — max trades per line, cool down between trades, automatic pending order cancellation when a trend line is deleted
- Trade life cycle monitoring — tracks fills, SL/TP hits, rejections, and cancellations with notifications for each event
UI
A toolbar appears on the chart (position configurable) with:
- Draw Trend Line — places a new interactive trend line on the chart
- 📊 Trades — opens a panel showing active trades, recent history, and stats
