Before you start
ATR means Average True Range, a measure of price movement. This calculator expresses stop distances, entry spacing and total moves in ATR units. The initial stop distance defines the base 1R unit.
Set the entry structure
Enter Stop distance (ATR), Scale-in every (ATR) and Maximum additional scale-ins. Additional scale-ins exclude the first entry: two additional scale-ins means up to three entries altogether.
Choose the size of each entry
Select a Scale-in sizing mode or Custom sequence. Multipliers are relative to the initial 1x position. A custom sequence such as 1, 0.5, 0.25 uses full, half and quarter-size entries; the last value repeats if more entries are needed.
Set the move to compare
Adjust Selected total move (ATR) and Comparison moves. Read total R alongside Average R per 1x, Total entries and Total position size. A larger combined R result can reflect greater exposure, not just a better trade.
Check the stop-out model
Compare Original stop, Combined 1R max-loss stop, Combined breakeven stop and the trailing or pullback models. Read the Stop-out risk panel. Changing the stop model affects that panel, not the selected-move profit calculation.
Review the required win rate
Check Assumed losing trade (R) and Expectancy targets (R). Make sure the assumed losing trade is consistent with the risk you intend to model; it is a separate input, not a guarantee that every loss is limited to 1R.
