What ATR, RSI, MACD, ADX, VWAP and other indicators measure, how to interpret signals, and where their limitations lie.
Short answers based on the ArapovTrade library. Each answer links to a detailed explanation. Trading approaches are presented as Igor Arapov's explanations; first-person wording refers to the author.
Which Trading Indicators Actually Work
What are trading indicators, and why do many lag price?
An indicator is a formula built from past closed candles, so by nature it shows what the market has already done; the lag is not a settings defect but a property, and the ceiling of an indicator is describing the past.
Why does the author avoid entries based only on indicator crossovers?
Crossovers of the stochastic , MACD, and movings feel like they work on the first trades, but over a hundred to three hundred trades they come out like a coin flip with no durable edge; I do not build an entry on them, I look at the level and volume.
What are regular and hidden divergence on a chart?
Divergence is a disagreement of price and an indicator: price gives a new extreme while the indicator does not; bullish hints up, bearish down, hidden at continuation, but it is a hint of a weakening impulse, not an entry point.
Why does the author require confirmation beyond indicator divergence?
On an indicator divergence lags and in a strong trend gives false signals; on gold 4H I do not enter on divergence alone, I wait for the level, a reversal candle, and volume, and it is more honest to look at the disagreement of price with volume rather than with an oscillator.
Which volume and volatility tools does the author find useful?
Volume and volatility (ATR) are useful, because they show the cause, not the trace; an oscillator by definition catches up to the market, so I build the decision on levels and volume, while an indicator only complements but never replaces an understanding of supply and demand.
How Strong Is the Current Trend
What does ADX measure?
ADX is a line that measures only the strength of a move, not its side; the scale runs from zero to one hundred, and it is itself a consequence, not a cause: price is moved by volume and the actions of a big participant, while ADX merely reads the result.
How does the author interpret ADX as a trend-strength filter?
Above twenty-five is usually a trend, below twenty a range; ADX counts how strongly one side outweighs the other, but this is a recalculation of a move that has already happened, so it lags and suits a filter rather than a leading signal.
How do +DI, -DI and ADX threshold levels differ?
+DI and -DI show the side (who is stronger, buyers or sellers), while the ADX levels show strength: below 20 a flat, 20-25 a nascent move, above 25 a trend, above 40 strong and often already overheated; all of it is a filter of conditions, not an entry signal.
How can ADX be used to distinguish trend and range regimes?
Use ADX to pick the regime: above 25 the market trends and trend-following and breakouts have a chance, below 20 it ranges and mean-reversion fits; a breakout with ADX rising through 25 has conviction, and a +DI/-DI crossover is only worth acting on with ADX above 25 and rising.
Why does a high ADX reading not provide an entry direction?
Do not enter a trade just because ADX is high: it does not know the side and often lights up already in the thick of the move; keep it as a filter of the flat, and take entry and direction from levels and volume.
How is ADX calculated, and what period is commonly used?
ADX smooths DX, an index based on the relative difference between +DI and −DI. A period of 14 is commonly used. Changing the period changes sensitivity but does not remove reliance on past price movements.
How to Use ATR to Measure Volatility
What does Average True Range measure?
ATR is the range of price averaged over fourteen candles; it runs high both in a rise and in a fall, so the side of the move cannot be read from it.
How does the author use ATR when choosing stop distance?
Hide the stop beyond the current ATR range, not under a local level: on a calm market it is tighter, on a stormy one wider, and noise stops sweeping it out.
How does the author combine ATR multipliers, position size and trailing stops?
Set the stop at a multiple of ATR (about 1.5x intraday, 2x swing, 3x position) and let the same range fix the position size, so risk in money stays even across calm and wild instruments; trailing a few ATRs below the high (the chandelier exit) lets a winner run while volatility is wide.
How does the author interpret an unusually high ATR reading?
ATR at a peak says the move has run out of breath: not a signal to close at once, but a reason to pull the stop to break-even and prepare the exit.
How does the author use ATR compression when watching false breakouts?
ATR compression before a session is a setup for a false break: price is led past the level to collect stops, and it pays to work against that break rather than after it.
How is a candle's True Range calculated?
True Range is the largest of the high minus low, the absolute difference between the high and previous close, and the absolute difference between the low and previous close. It accounts for gaps as well as the candle's visible range.
Why normalize ATR by an asset's price?
Absolute ATR depends on price scale and quotation units. Dividing it by price and expressing it as a percentage allows relative comparisons. The periods and timeframes being compared should also be consistent.
How does Chandelier Exit use ATR?
For a long position, the described approach places a protective stop several ATR units below the high reached during the move. The reference follows the developing price action. It is a volatility-based exit method rather than a reversal forecast.
Understanding the MACD Indicator
How is MACD constructed from moving averages?
MACD is the difference of the 12 and 26 averages plus the 9-period signal: visual and clear, but the whole neatness rests on the assumption that an averaged past will predict the future.
What are the main MACD signals described in ArapovTrade?
The four basic MACD signals are the line crossover, the histogram (momentum strength), the zero-line cross, and divergence (a price-indicator mismatch, bullish and bearish); divergence is the most valuable of them because it leads the reversal.
How do MACD settings and signal timing affect interpretation?
The default 12, 26, 9 is the place to start; faster settings and lower timeframes only add false crossovers; and among the signals the histogram slope leads while the zero-line cross trails, yet every one of them is still a lagging read of past price.
Why can MACD and stochastic readings conflict?
When MACD is right, what fires is not it but the level, the volume and the false break beneath it; and next to the stochastic it easily contradicts itself, since both are calculated from the same past price.
Why does the author treat MACD as background rather than an entry system?
MACD lags by construction, it is a derivative of what the market has already done, so keep it at most for background, and look for the edge in levels, volume and price action.
Why can MACD readings differ between minute and daily charts?
Each calculation reflects its own period, so a short-term pullback can conflict with a longer-term trend. In the author's approach, the higher timeframe provides context for interpreting the lower one.
How the Relative Strength Index Works
What is RSI, and what does its 50 line indicate?
RSI is an oscillator from 0 to 100 built from the average rise and fall over 14 candles; the central 50 line says more about the balance of forces than the 70 and 30 zones do.
Why are RSI readings above 70 or below 30 not automatic trade commands?
The 70 and 30 zones are not a command: in a trend RSI hangs in the extreme zone for a long time; first decide trend or range, then check the signal against a level and volume.
How does the author assess RSI divergence?
Divergence hints at a move fading, but solo it is unreliable and drags on; it works only in tandem with a strong level and an inflow of volume.
What limitations does the author identify in RSI entry signals?
RSI is calculated from closed candles and lags, knowing nothing of the news or a large player; it is a good thermometer of state but a poor generator of entries.
How does the author use RSI settings and thresholds in different regimes?
Start at 14 and don't chase a magic period; widen the bands to 80/20 in strong trends; mean-revert from 70/30 only in a range, lean on the 50 line for trend continuation, and let a level and volume make the actual entry.
What does the author's experience suggest about searching for perfect RSI settings?
There is no perfect RSI setting, there is context; keep it as a thermometer of state and look for the entry by a level and volume, not trading 70 and 30 against the trend.
What is the RSI formula in simple terms?
First calculate RS, the ratio of average gains to average losses. Then RSI = 100 − 100 / (1 + RS). For example, RS = 1.5 gives RSI = 60.
How to Read the Stochastic Oscillator
What do the stochastic oscillator's %K and %D lines represent?
The stochastic is a momentum indicator: it compares the close with the range of highs and lows over a period and plots two lines from 0 to 100, where %K is the main one and %D the smoothed signal.
How are stochastic settings such as 14, 3, 3 interpreted?
%K measures where the close sits in the recent high-low range from 0 to 100 and %D is its smoothed signal line; the default 14, 3, 3 (the slow stochastic) is the sane starting point, faster settings only add noise, and there is no magic number.
What do stochastic zones, crossovers and divergence describe?
The stochastic has three signals: zones above 80 and below 20, the %K and %D cross, and divergence; but overbought is not a command to sell, only price closing near the top of its range.
How does the author use stochastic differently in ranges and trends?
In a range the stochastic reliably works the zones of 80 and 20, while in a strong trend it sticks to the extreme zone and generates signals against the move, so in a trend I watch it only with the trend.
Why does the author avoid stacking stochastic and moving-average signals?
Indicators are derived from one price and lag, so stacking them on each other only piles up a muddle; instead I read volume and levels, since volume is the cause of a move, not its trace.
Simple vs Exponential Moving Averages Explained
How does a simple moving average differ from an exponential moving average?
An average is an averaged line of past prices; the SMA is smooth and slow, the EMA faster thanks to the weight on fresh data, but both speak of the past.
What limitations does the author identify in moving-average entries?
An average reports a reversal after the fact, and in a range it scatters false signals, and no ideal setting exists between noise and lag.
How does the author assess moving averages as dynamic support or resistance?
People trade an average as dynamic support or resistance, buying the pullback to a 21 or 50 EMA; it works partly because everyone watches it, but the line slides every candle, so I treat it as context and trust a real horizontal level and volume instead.
How can a 200-day moving average serve as a long-term trend filter?
The one honest role of an average is a rough trend filter on long horizons, such as the 200-day SMA, but as an entry signal it's no good.
What are the Golden Cross and Death Cross?
A Golden Cross occurs when a faster moving average crosses above a slower one; a Death Cross is the reverse. The 50-period and 200-period averages are commonly used. The author treats these as market-regime references and accounts for their lag.
Using VWAP to Time Entries and Exits
What is VWAP, and why does it usually reset each session?
VWAP is the volume-weighted average price from the session open: where more trades went through, that price weighs more; it's counted cumulatively and resets each day, so it's primarily an intraday tool.
How can institutions use VWAP as an execution benchmark?
A large fund stretches its execution and grades it against VWAP, so algorithms build the position around the average; those who bought above are glad to exit at breakeven on a pullback, and because of that price returns to VWAP so often.
How does the author interpret price above or below VWAP?
Price above VWAP is a buyers' edge, below it a sellers' edge, on the line itself balance; the bands of one to three deviations hint at being stretched, but that's not a button, and without volume confirmation I don't enter off them.
How does the author assess a VWAP reclaim or rejection?
VWAP is unreliable in the first 15-20 minutes and on thin names, and the five-minute chart is its usual home; rather than the bare touch, I read the reclaim or rejection of the line and let the volume on it decide whether the move is real.
How does Anchored VWAP differ from session VWAP?
An anchored VWAP is the same VWAP but measured from a chosen point (a swing, news, the week's open) and with no daily reset, so it works for swing trading on higher timeframes, not only intraday.
How does the author combine VWAP with horizontal levels and volume?
VWAP's strength appears at a coincidence with a horizontal level and a large volume, where three confirmations converge; for me it's an add-on to volume and levels that conveniently highlights the session's fair price, not a separate system.
How Bollinger Bands Measure Volatility
What do Bollinger Bands measure?
The bands are a thermometer of volatility set two standard deviations from the average; they show the size of the move but stay silent about its direction.
Why is touching a Bollinger Band not an automatic trade signal?
A touch of the band is not a signal: in a trend price walks along it for a long time, so at the edge I first read the phase, the level and the volume.
What does a Bollinger Band squeeze indicate?
A squeeze is an attention signal, not a direction one: the market is gathering strength, but it shows the side with a hold and volume, not with the first false break out of the channel.
How do BandWidth and Keltner Channels help identify a squeeze?
BandWidth puts a number on the squeeze and a Keltner Channel overlay turns it into a rule (bands inside means on, outside means it fires), but a measured squeeze still only flags that a move is loading, never its direction.
How does the author combine Bollinger Bands with levels and volume?
The trio of band plus volume plus level separates a real breakout from an exhale, and one line on its own cannot do that.
Reading the Ichimoku Kinko Hyo Indicator
What does the author say about Ichimoku's five lines?
The five Ichimoku lines are kinds of moving average shifted in time; the pretty wrapper doesn't change the fact that they're computed from past price.
How is price interpreted above, below or inside the Ichimoku cloud?
Price above the cloud is trend up, below it down, inside it a range; but what the cloud calls support usually coincides with an ordinary horizontal level.
How does the author assess a Tenkan-Kijun crossover?
The TK cross is a crossing of two averages after the fact: by the time the signal lands the move is already done, so I take it only with the trend, against the trend never.
Why does the author suggest learning direct chart reading before Ichimoku?
It's easy to learn, but a beginner is better off not starting with it: trend and levels read faster directly, and you can return to the cloud later if you want.
