Overview
When bar timestamps fall between the years 2015 and 2016, it submits concurrent long and short entries under a single OCA group named Entry. Because the group uses the cancel type, executing one entry automatically cancels the opposing entry order. The script contains no indicators, exit rules, or stop loss orders, serving purely as a basic syntax template for OCA order management.

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