The system jumps in the direction of any bar that closes more than one ATR(10) away from the previous close, long or short. It exits when price closes back through a 5-period SMA or hits a 1% stop, and it trades intraday on index and gold charts.

The code
Every file in the library uses the same header, the same section order and the same variable names. The numbers above were produced by the original version before the rewrite, and the rewrite has not yet been compiled in ProRealTime.

Questions
The code runs as a ProOrder system with 1 contract and a 1% stop. Given that no tested run was profitable, it makes more sense as a study piece than a live system.
Gold, S&P 500, DAX 40 and Nasdaq 100 on 5, 15, 30 minute and 1 hour charts. All 15 runs ended negative, and Gold lost the least.
On the S&P 500 30 minute chart the maximum drawdown was EUR 13,587.60 trading 1 contract. On DAX 40 15 minutes it reached EUR 47,829.60.
A one-ATR bar on a short chart is a frequent event, which gives thousands of trades to judge the idea. Here the higher trade count mainly made the losses clearer.
