How Qing LRC + S/R + EMA (Trend Cross Logic) 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 acts only when several checks agree at once. It leans on EMA, linear regression, pivot high, pivot low; 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. It gets out when another set of checks agrees. That line is in the list below too.

Each trade uses a fixed 1000 of the quote coin. It holds one trade at a time.

The exact condition, from the code

Same rule, translated from the code, in the author's names. You can skip this list if the paragraph above was enough.

Enters long when upper channel is above the 20-period EMA of the close and (the low is at or below lower channel or the low is at or below (last s × 1.02)) and the close is above the open and the number of open trades equals 0.
Closes the position when (lower channel is below the 20-period EMA of the close or the high is at or above upper channel) and a long position is open.

Buys or sells	It only buys. It does not bet on falling prices.

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 68 cells. It placed a trade on 66 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.

Cells tried	68
Cells that placed a trade	66
Finished above zero	0 (0.0% of the cells that traded)
Middle result, before fees	−2.0%
Strongest cell, the top of the range	XRP daily: −0.5%
Weakest cell, the bottom of the range	ADA daily: −6.7%
Middle drawdown, before fees	1.6%

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 1.6%.

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.
