The books... not free though
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.

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.
