Overview
All alert() calls marks an RSI cross above 50 with an up triangle and an RSI cross below 50 with a down triangle. When a cross occurs, it calls alert with a long or short message that includes the current RSI value. There are no entries, exits, stop loss, take profit, or position sizing, and no user inputs are defined.
