Trendline Rebounder

Trading robot that looks for price rebounds off trendlines, not breakouts. Built for Scalping on BTCUSD with 5-minute candles. All its parameters are already optimized, but you can change them to taste.

How it operates

1. Draws support and resistance lines automatically. The robot looks at recent price highs and lows and draws lines connecting them (like you'd do by hand on a chart, but calculated mathematically for greater precision).

2. Waits for price to touch a line and bounce.

   • Touches a support line (below price) and the candle closes above it → BUY signal.
   • Touches a resistance line (above price) and the candle closes below it → SELL signal.

3. Requires volume confirmation. Only enters if that candle's volume exceeds the recent average, to avoid weak bounces with no real force behind them.

4. Only one open trade at a time. If both buy and sell trigger on the same candle, the robot does nothing — avoids a blind coin-flip.

5. Manages risk on its own, candle by candle:

   • Stop loss: cuts the loss at a defined distance.
   • Take profit: closes in profit at a defined distance (optional).
   • Break-even: moves the stop near entry once the trade is already in profit, so it can't turn into a loss.
   • Trailing stop: follows price as profit grows, protecting the gains.

Input parameters

Trendlines

• Evaluation zone: how far from the current price it looks for points to draw lines.
• Lookback bars: how much history it scans to find those points.
• Top N: how many good-quality lines it keeps per side (support/resistance).
• Minimum touches: support points needed for a line to be valid.
• Max violations: how many times price can "pierce" the line before it's discarded.
• Touch tolerance: how close price must pass to the line to count as a "touch".

Measurement unit

• All distances (stop, take profit, etc.) are measured in ATR by default, a measure of how volatile the market is at that moment. This way the robot adapts on its own whether the market is calm or agitated.

Confirmation

• Average volume: compares current volume against the average of the configured recent candles.

Direction filter

• Allows buys and sells freely, or can be restricted to only trade with the trend (measured with a moving average), buy-only, or sell-only.

Stop loss / Take profit

• Stop loss and take profit distance, each one switchable on or off.

Break-even

• Activation distance (how much profit is needed to move the stop) and the point where the stop is left.

Trailing stop

• Activation distance and the distance it keeps from price while following the trend.

Money management

• Trade size calculation mode: risk as a percentage of capital, or fixed lot.

General

• Magic number (internal identifier for the robot's trades).
• Maximum slippage allowed when sending orders.
• Whether to draw the lines on the chart.
• Verbose activity logging (on/off).

General recommendations

• In the default configuration, the robot risks 5% of capital per trade. If that seems excessive, you can lower the risk to your liking.
• If you want to use a different asset and a different timeframe, I recommend backtesting and optimizing the robot's parameters mentioned above beforehand.
