How does the ATR indicator account for the gaps between the candles?
A regular bar has a high, a low, and a close. The high-low difference shows the intraperiod range but misses a gap when a new bar opens far from the previous close. J. Welles Wilder addressed this problem with True Range.
For each candle, three values are compared:
- The current maximum minus is the current minimum.
- The absolute difference between the current maximum and the previous shutdown.
- The absolute difference between the current low and the previous close.
TR = max(high - low, abs(high - previous close), abs(low - previous close))
Absolute value takes away the sign. The distance is important to the calculation, and the direction at this point is outside the formula. If the candle completely covers the previous range, it usually wins the high-low. After breaking up or down the longest can be the distance from the new extreme to the previous close.
True Range is then averaged. On TradingView, the standard ATR indicator uses a 14-period RMA, Wilder’s smoothing method. The platform settings also offer other moving-average types. The detailed smoothing mechanics are covered in the guide to Moving average in trading.
What changes the period 14 and the smoothing?
The number 14 represents the number of calculation periods, and the time unit depends on the chart. Five minutes. The timeframe It gives a window at 70 minutes, a clock at 14 hours, a day at 14 business days. The same number describes different market scales, so the setting is always recorded along with the timeframe.
The first value has a starting point. ChartSchool shows the classic order: the first 14 True Range are averaged, then the new value is smoothed through the previous ATR. The deeper the history of the calculation, the less impact the starting point has. Because of the different data depth and rounding, the two platforms are able to show close but not entirely identical numbers.
Wilder's RMA retains more memory of past ranges. EMA responds more strongly to fresh values, SMA moves the window with equal weights. Changing the middle type changes the nature of the line, so it only makes sense to compare results with the same settings.
Standard 14 is a good starting point for observation. It doesn't become a one-size-fits-all asset. Check starts with fixed parameters and a series of closed bars. Then change one parameter at a time, or the result will be easily traced to the selected part of the story.
How do you read the rise and fall of volatility?
ATR rises after both a sharp increase and a sharp decline in price because either move expands the range. A high reading therefore cannot be translated into a buy or sell signal. ATR answers a different question: how large have recent moves become relative to the instrument’s own history?
A low value means the ranges have contracted. This is common in a sideways market, but low the volatility He doesn't promise a close one. Breakout. Compression may last longer than expected, and the direction of the future breakout is unknown in advance. To evaluate the mode, it's useful to watch The Bollinger bands, the structure of the high and low and confirmation by volume.
The increase after compression indicates that the motion is gaining amplitude. The direction is checked on price and the market share is checked on price. the volume indicator. So three observations answer different questions and don't duplicate each other.
| Watching | What We Know | What we don't know yet |
|---|---|---|
| Growth of ATR | The ranges are expanding | Where 's the price going? |
| Reducing the ATR | The ranges are narrowing. | When and which way to go. |
| Stable ATR | The scale of the candles is close to the recent norm | whether the regime will be maintained after the next event |
Why do you need an ATR% when you compare assets?
The value of 10 can be a small ATR for an expensive instrument and a huge ATR for a cheap one. A comparison without normalization mixes the price scale and the scale of the fluctuations. TradingView and StockCharts offer an interest rate option:
ATR% = ATR / close * 100
If the ATR is 2, and the closing price is 100, the relative the volatility That's two percent. If another instrument has ATR 20 at the price of 2000, its ATR% is equal to 1%. The absolute value of the second is higher, although relative to its own price the first instrument moves wider.
A typical ATR indicator is convenient within one asset: the distance is expressed in the same units as the price. Different tools compare through ATR%, but only on the same timeframe and with the same calculation period.
How can ATR be used for a stop without treating it as a signal?
The simplest approach starts with the price invalidation point. For a long position it can be below the local minimum, for a short position it can be above the local maximum. Then the distance is compared to the current ATR. If the usual fluctuation easily affects the chosen level, the stop is too sensitive to market noise for this logic.
In some strategies, the ATR indicator specifies the distance of a species. k * ATR Where? k - a pre-selected multiplier. This standardizes the volatile stock, but it doesn't create the trade idea itself. The same multiplier behaves differently in trends, side effects, news impulses, and timeframes.
Useful order of action:
- Determine the price level of cancellation.
- Measure the distance from the presumed entrance to this level.
- Compare the distance to the current ATR in the same timeframe.
- Check the rule on a series of historical sites without changing parameters.
- Calculate the size of the position from the acceptable monetary risk, not from the desire to get more.
The ATR is not a level replacement. It adds to the level information about how widely the price has moved recently.
How do you relate position size to volatility?
The logic of the calculation is simple: first, you choose the amount that the rules allow you to lose when you start the stop. This amount is then divided by the distance to the stop in monetary units per unit of asset. Commissions, slippage and contractual features are taken into account separately.
Position size = acceptable monetary risk / distance to the stop
A conditional example is only needed for mechanics. At a risk of 100 units and a distance to the stop of 5 units, the calculation gives 20 units of an asset before correction. If the volatility increases and the justified stop expands to 10 units, the size decreases to 10. The monetary risk remains the same.
The dangerous error occurs in the opposite order: first, the desired volume is selected, then the stop is moved so that the trade fits. Then the volatility stops controlling the distance, and the risk becomes random. For comparison with the trend context, the article on MACD But neither the momentum nor the trend can remove the limit of losses.
Where is the ATR in the Midas system?
Midas Up is responsible for the direction and areas of interest. It brings us together. the trend, levels, volume profile and liquidity. Midas Down helps evaluate the moment through cash flow, momentum, trendline, volume delta, and aggregate overbought or oversold estimates.
The food source indicates that the stop is calculated individually by volatility and ATR. The only thing that follows is the role of the volatile scale. The exact coefficient, weight and order of internal calculations are not publicly stated, so the article does not invent them.
The Midas signal remains a trigger for attention. The user's decision is based on strategy rules, confidentiality and permissibility. The risk. Map of other instrument classes is in review Indicators for trading. If the edge of the oscillator is important to the idea, check separately. overbought and resold.
How do you check the settings in 15 minutes?
- Open one liquid instrument and choose a permanent one The timeframe.
- Add Average True Range with its standard 14-period setting.
- Find an area with narrow candles and an area with a wider range.
- Notice how ATR reacted to the ups and downs and the price gap.
- Write the absolute value and the ATR% at the same point.
- Compare the distance to the technical level with the current ATR.
- Check at least 20 closed-bar observations without changing the setting after each result.
Check ATR only on closed bars. During the current period, high, low, and close continue to change, so True Range and ATR are not final. Record price direction, volatility regime, and the result of price confirmation separately. This turns the line from a ready-made signal into a measurement tool.
Risks and Restrictions
A sharp news-driven impulse can widen the range instantly, while the smoothed line catches up later. After a spike, ATR may remain high even when current bars have already calmed down. During prolonged compression, low ATR may remain low without a breakout.
Absolute values depend on the price scale. For cross-market comparisons, you need ATR%, the same period and the same timeframe. Even after liquidity is normalized, the trading hours and device of the instrument remain different.
A stop for volatility does not protect against price breaks, slippage or execution errors. A history check does not guarantee a repeat. Any calculation of the size of a position requires its own rules of risk.

Frequently asked questions
What does ATR show in simple terms?
ATR shows the average true range over a selected number of bars. The higher the value, the wider recent moves have been in price units. The line accounts for gaps relative to the previous close, but it does not say whether the next move will be up or down. ATR is therefore read as a measure of range: it suggests what amount of movement is normal for the instrument and timeframe, while direction is assessed from price and market structure.
Why is the standard period equal to 14?
Period 14 is rooted in Wilder's classic approach and is used by platforms as a launch setting. Each timeframe covers a different real time. The period should be checked on a particular instrument's data series without continuous adjustment.
Is it possible to compare the ATR of two assets?
Comparing raw values is incorrect because ATR is expressed in units of price. For relative comparison, ATR is used, calculated as ATR divided by close and multiplied by 100. The timeframe and the period must match. Then the comparison answers the obvious question: what proportion of the current price occupies the usual candle size of one instrument and the other.
Does rising ATR mean rising prices?
No. ATR rises when ranges expand in either direction. A sharp rise and a sharp fall can increase the line equally. Direction is read from price, trend, and market structure. A rising ATR only says that the market has begun moving more widely than usual and that the previous protective boundary may now be too tight.
Which ATR multiplier to choose for the stop?
There is no universal multiplier. It's checked along with the invalidation price, the timeframe, the asset and the acceptable risk. First they fix the rule, then they check a series of historical sites and change only one parameter at a time. Too small a multiplier knocks out the trade with the usual noise, too big a risk inflates, so the point of selection is to find a boundary that experiences normal fluctuations.
Does low ATR promise an imminent breakout?
A low value confirms that recent ranges have contracted. It does not specify the timing or direction of the breakout. Compression may continue, so price confirmation, a level, and independent context are required. In practice, low ATR is more useful as a warning of a regime change: while the range remains small, targets and stops calculated for a wider market may no longer fit.
Can I use ATR with Midas?
You can compare the volatile scale to the multilayered context of Midas. The product source indicates the ATR in the individual stop-loss calculation, but a single value is not a signal for the entire system. The rules for risk and indoor candlestick inspection remain mandatory.
