Whether you use daily or hourly ATR depends on how long you plan to hold the trade. For intraday or short-term trades (held a few hours to one day), look at the 1-hour or 4-hour ATR. For swing or trend trades (held several days to weeks), use the daily ATR. You can watch both timeframes, but know which one is your primary and which is secondary.
Step 1: Identify Your Holding Period
This is the key to choosing the right ATR timeframe.
Case A: You hold for less than 24 hours (for example, trading breakouts on a 15-minute or 1-hour chart). Use the 1-hour ATR as your main reference. This timeframe captures volatility differences between the Asian, European, and US sessions, helping you set a sensible intraday stop-loss.
Case B: You hold for more than 24 hours, possibly several days (for example, trend-following on a daily chart). Use the daily ATR as your main reference. Daily ATR filters out intraday noise and reflects the market's average daily range, making it better for swing trades.
Checkpoint: Be clear about which case your trade falls into.
Step 2: Set the Stop-Loss Based on the Matching ATR
Now you should have the ATR indicator on your chart (default parameter 14).
Action: Switch your main chart to the timeframe you chose above, and note the current ATR value.
Formula: Stop-loss distance = current ATR × multiplier. For intraday trades, use 1 to 1.5 times ATR to avoid being stopped out by random wicks. For swing trades, use 2 times ATR to give the trend enough room to pull back.
Checkpoint: Your stop-loss order is placed at a distance calculated from the ATR on your main trading timeframe. Do not grab a number from a different timeframe on a whim.
Common mistake: Opening a position on the daily chart but setting the stop-loss using the 15-minute ATR. A normal daily pullback can easily exceed 2 times the ATR on a 15-minute chart, making your stop too tight and getting you knocked out often. The reverse also hurts: using the daily ATR for a scalp gives you a stop so wide it offers almost no protection.
If you refer to two timeframes, watch out for this risk: the hourly ATR spikes higher while the daily ATR barely moves. This means the volatility is a short-term event. Do not widen your swing stop-loss to an unreasonable level because of it. On the other hand, if the daily ATR starts climbing, it signals that medium-term volatility is picking up. Both your position size and stop-loss need to be adjusted accordingly.
How to Verify After Placing the Trade
Once the order is placed, keep your main chart and the ATR reference timeframe the same. Next time you check the stop, make sure you are not judging the price distance on a different timeframe. If the price does not hit your stop within 2 or 3 bars on your main chart, the stop distance is appropriate for the current rhythm of volatility.
Follow-Up Adjustment Rule
At the close of each bar on your main trading timeframe (for example, every hour if you use a 1-hour chart), check the ATR value. If the ATR has changed by more than 15% since you placed the trade, recalculate the stop distance using Step 2. If not, leave it unchanged.
