How HalfTrend + Hull + BB (Pure Arrow Mode) works
Rules in this group usually work like this. It waits until price is already moving, then joins that move. It is wrong in small ways many times, and right in a large way a few times. The hard part is the stretch where price chops around and every entry is a fake. The next paragraph is this particular rule, which can be narrower than the group.
It only buys. It does not bet on falling prices. It buys when trend equals 0 and the previous trend equals 1. It gets out when trend equals 1 and the previous trend equals 0.
The author did not set a size, so each trade uses whatever amount the code assumes. It holds one trade at a time.

How the backtest was run
Every strategy was tried the same way, on the settings the author published.
The years are October 2021 to June 2026. The prices are from Bybit, for 13 widely traded coins, mostly on hourly, 4-hour and daily charts, with some faster charts. That was 47,242 tries. The window stored in the files is 2021-09..2026-06.
599 rules produced a finished try. A rule that finished above zero on at least 12 cells, before any fee, was tried again with a fee of 0.12 percent per side. Only buys are counted in that second try. 273 rules got it.
The method, the aggregate results and a downloadable table are on the study page. What the desk does with the results beyond these pages is its own.

How to read the result
How to read the number
No cell took a trade, so there is no return to read. The rule above is the whole note.
What this does not show
The useful question, for a rule that joins a move already underway, is what it gave back in the choppy months when there was no trend to join.
There is no cell to single out, and this note does not invent one. Other years, another exchange, or another fee would be a different measurement.
