Overview

When no position is open, the strategy uses a pseudo-random function to trigger long entries. Upon entering, it immediately establishes a trailing stop exit based on the current bar close price plus one tick. The script draws directly on the price chart and includes no customizable settings or hard stop loss protection.

Indicators describe the past, and a strategy's backtest can look better than live trading, especially when a script repaints.
