How Dow & Granville's Strategy 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 can buy, and it can bet on falling prices. It acts only when several checks agree at once. It leans on SMA; those names are explained on their own pages, further down. The exact line is in the list below, in the author's names, and you can skip that list.

The author did not set a size, so each trade uses whatever amount the code assumes. It holds one trade at a time.

The exact condition, from the code

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.

Before any fee, it was tried on 69 cells. It placed a trade on 3 of them. 0 of the cells that traded finished above zero (0.0%).

It was not run a second time with a fee. That second pass happens only when at least 12 cells finished above zero before fees. 273 rules got that pass.

How to read the result

How to read the number

The median of every cell that traded is the result. No fee has been taken off, so the number is a ceiling. A fee comes off each trade, and this page does not guess that cost, because this rule did not get the second pass where the fee is applied. The weakest and the strongest cells are not a result on their own.

The middle drawdown, on the cells that traded, was 0.0%.

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.

Nothing on this page was fit to the cell that finished highest. One coin, one chart speed, or one strong stretch is a single row. It is not the rule. Other years, another exchange, or another fee would be a different measurement.
