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 Williams R Zone Scalper v1.0[BullByte] works

Rules in this group usually work like this. It takes a lot of small trades on fast charts and needs a tiny gain on each one. The trading cost is the whole story. With no fee, almost every rule of this kind looks fine. With a real fee, many do not. A test on one-minute bars also assumes every order was filled, which is generous. 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, Hull MA, RMA; 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 30 percent of the 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 Williams %R of Williams %R Length (14) crosses above −80 and filter long.
• Enters short when the Williams %R of Williams %R Length (14) crosses below −20 and filter short.
• Places a stop at (last entry price − (the 14-period ATR × SL ATR Multiplier (1.5))), a target at (last entry price + (the 14-period ATR × TP ATR Multiplier (2))) when the Williams %R of Williams %R Length (14) crosses above −80 and filter long and Enable SL/TP (off).
• Places a stop at (last entry price − (the 14-period ATR × SL ATR Multiplier (1.5))), a target at (last entry price + (the 14-period ATR × TP ATR Multiplier (2))) when the Williams %R of Williams %R Length (14) crosses below −20 and filter short and Enable SL/TP (off).

Buys or sells	It can buy, and it can bet on falling prices.
Tools it calculates	ADX / DMI, ATR, EMA, Hull MA, SMA, Standard deviation, Supertrend, WMA, RMA, Williams %R
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 30 percent of the account.

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.

This is the second pass. A fee of 0.12 percent per side is taken on the buy and again on the sell. Only buys are counted. If the rule also bets on falling prices, those trades are not in these numbers.

After fees, 23 of 65 cells finished above zero (35.4%). The median of every cell was −19.9%.

14 of the cells cleared a quality check: at least 50 trades, gains that are not one lucky trade, and a drawdown that is real without taking the whole account.

Finished above zero by chart speed: 15-minute chart, 15m 0 of 13; daily chart, 1D 7 of 13; hourly chart, 1h 5 of 13; 30-minute chart, 30m 2 of 13; 4-hour chart, 4h 9 of 13.

Cells tried after the fee	65
Finished above zero	23 (35.4%)
Middle result, the median of every cell	−19.9%
Middle drawdown, every cell	49.2%
Cells that cleared the quality check	14
Middle result, over the cells that cleared the quality check	+23.2%
Extra, Calmar on the checked rows. Result divided by the deepest fall	0.60
Extra, Sharpe on the checked rows. Result divided by how bumpy the path was	0.05
Middle drawdown, the checked rows	53.1%
Deepest fall, the checked rows	97.9%
Middle number of trades, the checked rows	129

How to read the result

How to read the number

The median of every cell is the result of the rule. The author's settings were not changed to help any coin. The weakest and the strongest cells are not a result on their own.

What the number leaves out

The table also shows +23.2%, taken only over the cells that cleared the quality check. Cells that finished down are left out of that figure, which is why it stands away from the median of every cell. It describes those rows only.

14 of 65 cells cleared a quality check: at least 50 trades, a profit factor that is not one lucky trade, and a drawdown that is real without taking the whole account. Profit factor means the gains divided by the losses. Clearing the check describes this sample. It says nothing about the next set of years.

The count above is also split by chart speed. A speed that finished higher, in these years, is one slice of the same rule. It is not a separate strategy.

What this does not show

The useful question is the result after a real fee. With no fee, almost every fast rule looks fine.

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 Williams R Zone Scalper v1.0[BullByte]

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 Williams R Zone Scalper v1.0[BullByte] uses

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

• ADX and the directional movement index: how strong the trend is, not which way
• ATR (average true range): the volatility number behind most stops
• Exponential moving average (EMA): what it measures and where it misleads
• Hull moving average (HMA): how it removes lag, and what it costs
• 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
• Supertrend: an ATR trailing line that flips with the trend
• Weighted moving average (WMA): linear weights, less lag, and the price of it
• Wilder's smoothing (RMA): the average inside RSI, ATR and ADX
• Williams %R: the stochastic turned upside down
