What this script says

Tick Scalper is a strategy that trades XAUUSD on 1-minute bars, checking its rules on every price change. It holds at most 1 open trade.

You can change one input: `max_stretch` (default 2.0).

When the close crosses above VWAP (at most once per bar and waiting at least 2 bars between actions), it buys at market, risking 0.5% of the balance, with a stop 30 points from the entry, with a target 1.5R from the entry and kept hidden from the broker until it triggers.

On every price change, it checks whether not the bar has closed and the close is below VWAP minus the 14-bar ATR × `max_stretch` and, if so, closes all long trades.
