ATR (Average True Range)
ATR, or Average True Range, measures the average distance a market travels over a chosen number of periods, including gaps. It is a pure volatility reading with no directional bias. Traders use ATR to set stop distances that respect normal noise, to size positions consistently, and to judge whether current conditions are unusually quiet or unusually fast.
Full explanation
ATR is typically calculated over 14 periods on the timeframe being traded. Common applications are a stop set at a multiple of ATR beyond the entry structure, targets expressed in ATR multiples, and position size derived from account risk divided by the ATR-based stop distance. Rising ATR signals expanding ranges and often trend activity; falling ATR signals compression that frequently precedes a breakout.
Why traders watch it
Stops placed without reference to ATR are guesses. Sizing to ATR keeps risk per trade steady whether the market is calm or turbulent.

Breakout
A breakout occurs when price moves decisively beyond a defined level such as a range high, trendline or consolidation boundary. It signals that the balance between buyers and sellers has shifted and can start a sustained move. Breakouts also fail often, so traders look for confirmation through follow-through, expanding range and a successful retest of the broken level.
Momentum
Momentum describes how strongly price is moving in one direction. Strong momentum suggests buyers or sellers remain firmly in control and that a move is likely to continue. Weakening momentum, where each push travels a shorter distance than the last, often warns that a slowdown, pause or reversal is approaching even while price is still rising or falling.
Moving Average
A moving average smooths price into a single line by averaging recent closes, making the underlying direction easier to see. Simple and exponential versions are the most common, with the exponential type reacting faster to new prices. Traders use moving averages to define trend, to locate dynamic support and resistance, and to time pullback entries.
Pullback
A pullback is a temporary move against the prevailing trend before it resumes. It gives trend traders a lower-risk entry than chasing an extended move, because the stop can sit behind nearby structure. The judgement is always the same: is this a pause within a healthy trend, or the start of a genuine reversal?
