US500 BUY is a trading bot designed for the US500 index that employs a volatility-adaptive scaling-in strategy. It initiates up to 25 positions in stages as the price declines by 1%, 2%, and 3% from the initial entry, spacing trades by 1.5 times the Average True Range (ATR) to prevent overcrowding. Each position targets a fixed profit of 1.5 pips, aiming to capitalize on minor price pullbacks. The bot maintains continuous market exposure by automatically replacing closed positions. This approach is suited for ranging markets, focusing on small price reversions while managing risk through systematic position scaling. The combination of fixed profit targets and ATR-based entry spacing provides a disciplined, mechanical scalping method for trading the US500 index.
