ATR Trailing Stops for Hyperliquid Spot + Perps [HYPR-run]DESCRIPTION:
A drop-in ATR trailing exits module. Four architectures that maximize
profit on winning trades using volume weighted volatility instead of fixed levels or
plain ATR. Built modular; the trailing logic is self-contained so you
can drop it into any existing indicator or strategy as a plug-and-play
exits block. Two independent stops (long/short), spot and perps.
DISCOVERING EDGE
ATR trailing exits are popular, everyone uses them, but this indicator doesn't just trail on volatility, it trails on meaningful volatility that very few people measure. In order to gain a persistent, mechanical edge in how winners run and protect capital on the trades that don't work, we explored a more meaningful expression of ATR trailing exits.
VOLUME-WEIGHTED ATR vs PLAIN ATR
Plain ATR treats every candle equally. Volume-weighted ATR will only expand stops when volume validates the volatility, preventing premature exits on noise and letting winners run further on real moves. Over hundreds of trades this single difference can compound in the spirit of letting winners run further, losers stay controlled versus fixed levels or vanilla ATR.
- Four modes (A3.1, A4.0, A4.1, A4.2) cover different trailing
behaviors: ratcheting, chandelier anchor, free-floating, and raw
baseline. All size stop distance from volatility, not fixed levels.
- Modular engine. The trailing logic is self-contained; drop it into
any existing indicator or strategy as a plug-and-play exits block.
- Alerts fire built-in JSON webhook payloads. Paste your webhook URL,
create the alert, execute on the exchange of your choice.
ATR MODES
A3.1: LinReg + plain ATR, no ratchet. The baseline. Linear regression
projects where price is heading, plain ATR sets the distance. Stop moves
freely in both directions. Use as a reference or when you want a raw
trailing stop.
A4.0: LinReg + VWATR + Efficiency Ratio + ratchet (default). The
all-rounder. Volume-weighted ATR discounts low-liquidity candles. The
Efficiency Ratio (Kaufman) measures trend quality: in a clean trend it
widens the stop to let price run; in chop it tightens. Ratchet floor
means the stop only moves in your favor.
A4.1: Chandelier + VWATR + ratchet + first-bar multiplier. Anchored to
the highest high (longs) or lowest low (shorts). First-bar multiplier
sets a tighter initial stop, then the standard multiplier takes over as
the ratchet locks in gains. Use when entering off key levels.
A4.2: LinReg + VWATR, no ratchet. Same as A4.0 but without ratchet
floor or Efficiency Ratio. Stop moves freely with the projection, giving
the trade room through consolidation at the cost of less locked profit.
FEATURES
- Four ATR architectures selectable via dropdown
- Volume-weighted ATR: low-liquidity candles contribute less
- Efficiency Ratio: tightens in chop, widens in trend (A4.0)
- Ratchet floor: stop only moves in your favor (A4.0, A4.1)
- First-bar multiplier for tighter initial protection (A4.1)
- Separate ATR lookbacks for longs and shorts
- Separate multipliers for longs and shorts
- Two-bar confirmation prevents single-wick fakeouts
- Gradient fill between price and stop (intensifies near danger)
- Stop line color shifts with ATR regime (green stable, amber expanding)
- Ratchet circles mark each new locked-in level on the stop line
- Dashboard: mode, stop price, gap %, ER, VWATR %, regime state
- Dark/light theme toggle for any chart background
- Independent long/short alert toggles
- No JSON snippet needed; close payload is built into the script
HOW IT WORKS
Volume-weighted ATR scales each bar's true range by its volume relative
to the lookback average. High-volume bars contribute more; thin candles
contribute less. This prevents low-liquidity spikes from inflating stop
distance. Separate lookbacks for longs (default 14) and shorts (default
26) reflect that crypto drops faster than it climbs.
The Efficiency Ratio measures directional movement versus noise on a 0-1
scale. It scales the ATR multiplier between 0.8x (choppy) and 1.2x
(trending), adapting stop width to market regime. Only active in A4.0.
Two-bar confirmation requires a confirmed close beyond the stop level.
A single wick does not trigger the exit. The cross must hold for at
least one additional bar close.
ALERTS
Close Long fires as SPOT (sell spot position). Close Short fires as
PERPS (close short; spot is long-only). Toggle each independently.
Alert payload is built into the script as JSON; works with any webhook
receiver that accepts market/ticker/position fields.

adfuller(data, n_lag, conf)
: Augmented Dickey-Fuller test for stationarity.
Parameters:
data (array) : Data series.
n_lag (int) : Maximum lag.
conf (string) : Confidence Probability level used to test for critical value, (`90%`, `95%`, `99%`).
Returns: - `adf` The test statistic.
- `crit` Critical value for the test statistic at the 10 % levels.
- `nobs` Number of observations used for the ADF regression and calculation of the critical values.
___
The Augmented Dickey-Fuller test is used to determine whether a time series is stationary
or contains a unit root (non-stationary). The null hypothesis is that the series has a unit root
(is non-stationary), while the alternative hypothesis is that the series is stationary.
A stationary time series has statistical properties that do not change over time, making it
suitable for many time series forecasting models. If the test statistic is less than the
critical value, we reject the null hypothesis and conclude the series is stationary.

sharpness(forecasts)
The average width of the forecast intervals across all observations, representing the sharpness or precision of the predictive intervals.
Parameters:
forecasts (matrix) : The forecasted values in matrix format with at least 2 columns (min, max).
Returns: - Sharpness The sharpness level, which is the average width of all prediction intervals across the forecast horizon.
___
Sharpness is an important metric for evaluating forecast quality. It measures how narrow or wide the
prediction intervals are. Higher sharpness (narrower intervals) indicates greater precision in the
forecast intervals, while lower sharpness (wider intervals) suggests less precision.
The sharpness metric is calculated as the mean of the interval widths across all observations, where
each interval width is the difference between the upper and lower bounds of the prediction interval.
Note: This function assumes that the forecasts matrix has at least 2 columns, with the first column
representing the lower bounds and the second column representing the upper bounds of prediction intervals.

resolution(forecasts)
Calculates the resolution of forecast intervals, measuring the average absolute difference between individual forecast interval widths and the overall sharpness measure.
Parameters:
forecasts (matrix) : The forecasted values in matrix format with at least 2 columns (min, max).
Returns: - The average absolute difference between individual forecast interval widths and the overall sharpness measure, representing the resolution of the forecasts.
___
Resolution is a key metric for evaluating forecast quality that measures the consistency of prediction
interval widths. It quantifies how much the individual forecast intervals vary from the average interval
width (sharpness). High resolution indicates that the forecast intervals are relatively consistent
across observations, while low resolution suggests significant variation in interval widths.
The resolution is calculated as the mean absolute deviation of individual interval widths from the
overall sharpness value. This provides insight into the uniformity of the forecast uncertainty
estimates across the forecast horizon.
Note: This function requires the forecasts matrix to have at least 2 columns (min, max) representing
the lower and upper bounds of prediction intervals.

coverage(targets, forecasts)
Calculates the coverage probability, which is the percentage of target values that fall within the corresponding forecasted prediction intervals.
Parameters:
targets (array) : List of target values.
forecasts (matrix) : The forecasted values in matrix format with at least 2 columns (min, max).
Returns: - Percent of target values that fall within their corresponding forecast intervals, expressed as a decimal value between 0 and 1 (or 0% and 100%).
___
Coverage probability is a crucial metric for evaluating the reliability of prediction intervals.
It measures how well the forecast intervals capture the actual observed values. An ideal forecast
should have a coverage probability close to the nominal confidence level (e.g., 90%, 95%, or 99%).
For example, if a 95% prediction interval is used, we expect approximately 95% of the actual
target values to fall within those intervals. If the coverage is significantly lower than the
nominal level, the intervals may be too narrow; if it's significantly higher, the intervals may
be too wide.
Note: This function requires the targets array and forecasts matrix to have the same number of
observations, and the forecasts matrix must have at least 2 columns (min, max) representing
the lower and upper bounds of prediction intervals.

pinball(tau, target, forecast)
Pinball loss function, measures the asymmetric loss for quantile forecasts.
Parameters:
tau (float) : The quantile level (between 0 and 1), where 0.5 represents the median.
target (float) : The actual observed value to compare against.
forecast (float) : The forecasted value.
Returns: - The Pinball loss value, which quantifies the distance between the forecast and target relative to the specified quantile level.
___
The Pinball loss function is specifically designed for evaluating quantile forecasts. It is
asymmetric, meaning it penalizes underestimates and overestimates differently depending on the
quantile level being evaluated.
For a given quantile τ, the loss function is defined as:
- If target >= forecast: (target - forecast) * τ
- If target < forecast: (forecast - target) * (1 - τ)
This loss function is commonly used in quantile regression and probabilistic forecasting
to evaluate how well forecasts capture specific quantiles of the target distribution.

pinball_mean(tau, targets, forecasts)
Calculates the mean pinball loss for quantile regression.
Parameters:
tau (float) : The quantile level (between 0 and 1), where 0.5 represents the median.
targets (array) : The actual observed values to compare against.
forecasts (matrix) : The forecasted values in matrix format with at least 2 columns (min, max).
Returns: - The mean pinball loss value across all observations.
___
The pinball_mean() function computes the average Pinball loss across multiple observations,
making it suitable for evaluating overall forecast performance in quantile regression tasks.
This function leverages the asymmetric Pinball loss function to evaluate how well forecasts
capture specific quantiles of the target distribution. The choice of which column from the
forecasts matrix to use depends on the quantile level:
- For τ ≤ 0.5: Uses the first column (min) of forecasts
- For τ > 0.5: Uses the second column (max) of forecasts
This loss function is commonly used in quantile regression and probabilistic forecasting
to evaluate how well forecasts capture specific quantiles of the target distribution.
