Indigo is a fully automated, long-only trading bot designed for upward-trending instruments such as stock indices (e.g., US30, US500, NAS100). It uses the QQE (Quantitative Qualitative Estimation) indicator to detect momentum reversals from oversold conditions, executing market buy orders when bullish momentum resumes. The bot limits entries to one per bar and caps concurrent positions to control exposure.

Risk management is based on a dynamic ATR (Average True Range) stop loss that adjusts to market volatility. An optional ATR-based take-profit system allows partial position closure, followed by a trailing stop that secures profits as the price advances. Position sizing can be fixed or set as a percentage of account balance, automatically calculating lot size based on risk.

Key configurable parameters include QQE settings (period, smoothing, factors, thresholds), ATR-based stop loss and take profit, trailing stop, maximum open positions, and an invisible mode that manages stops internally to keep levels hidden from brokers.

Indigo suits intermediate to advanced traders familiar with ATR-based sizing and cTrader Automate, seeking a systematic approach to buying dips on indices. It supports any account size and is intended for swing trading with medium trade frequency. The bot does not open sell positions, hedge, or use grid logic. Backtesting on historical data is recommended before live deployment.
