Internal bar strength measures where the close sits inside the bar's range. When it is in the bottom 10%, the system buys, and it sells once a close finishes above the previous bar's high. It is long only.

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
Yes. It is a short piece of ProOrder code. It has been rewritten and not yet compile-checked, and the stats are from the earlier code.
Nasdaq 100 Daily made EUR 21,381.10 over 905 trades with a profit factor of 2.0. S&P 500 Daily had 1.74 and FTSE 100 Daily 1.4, and every row tested was profitable.
Nasdaq 100 Daily reached a max drawdown of EUR 2,532.40. S&P 500 Daily was EUR 674.45.
The idea is that a weak close often rebounds the next day. The three runs with a recorded profit factor are all on Daily bars.
