Every cell is in the picture, not only the strongest. To the right of the black line is above zero. The orange line, when you see one, is the middle.

How DEMA Trend Oscillator 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 ATR, EMA, SMA, standard deviation; 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. When it enters, it also sets a stop or a target, so a trade can close without a new signal.

Each trade uses the whole account. 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 the previous norm base is above Long Threshold (55) and the low is above (base + sd) and last direction differs from 'long'.
• Enters short when the previous norm base is below Short Threshold (45) and the high is below (base − sd) and last direction differs from 'short'.
• On entry, places a stop at (the 20-period SMA of dema + (the 20-period standard deviation of dema × 2)), a target at (the close + ((the close − (the 20-period SMA of dema + (the 20-period standard deviation of dema × 2))) × Risk Reward Ratio (1.5))), a trailing stop.
• On entry, places a stop at (the 20-period SMA of dema − (the 20-period standard deviation of dema × 2)), a target at (the close − (((the 20-period SMA of dema − (the 20-period standard deviation of dema × 2)) − the close) × Risk Reward Ratio (1.5))), a trailing stop.

Buys or sells	It can buy, and it can bet on falling prices.
Tools it calculates	ATR, EMA, SMA, Standard deviation
A second chart speed	No. It uses one chart speed only.
Only at certain hours	No.
Adding to a trade	It holds one trade at a time.
How much it trades	Each trade uses the whole account.
Cost the author assumed	The author assumed no trading cost.

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 67 of them. 7 of the cells that traded finished above zero (10.4%).

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	69
Cells that placed a trade	67
Finished above zero	7 (10.4% of the cells that traded)
Middle result, before fees	−66.7%
Strongest cell, the top of the range	SOL daily: +182.8%
Weakest cell, the bottom of the range	ADA 5-minute: −99.9%
Middle drawdown, before fees	86.1%

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 86.1%.

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.

Questions about DEMA Trend Oscillator Strategy

Words used on this page

Backtest

The rule was tried on old prices. No real money moved.

Cell

One coin on one chart speed. Bitcoin every 4 hours is one cell. Bitcoin once a day is another.

Chart speed

How often a new price bar is drawn. 15m means every 15 minutes, 1h means hourly, 4h means every 4 hours, 1D means once a day.

Fee, per side

A cost taken each time the rule trades. Per side means once on the way in and once on the way out.

Median

Line the cells up from the biggest loss to the biggest gain. The median is the middle one. Half the cells did better and half did worse.

Drawdown

The deepest fall from a high point along the way, as a percent of the account at that high.

Above zero

The account finished with more than it started.

The indicators DEMA Trend Oscillator Strategy uses

Each has its own page: what it measures, how it is read, where it misleads.

• ATR (average true range): the volatility number behind most stops
• Exponential moving average (EMA): what it measures and where it misleads
• Simple moving average (SMA): the plainest average, and why it still runs half the strategies
• Standard deviation in trading: the volatility measure inside Bollinger Bands and z-scores
