Position sizing determines how much money a trader is exposed to when a trade is wrong. Two traders can take the same setup and experience very different financial outcomes because they risk different amounts.
Start with the risk amount
Before entering a trade, decide how much capital you are prepared to lose if the stop-loss is reached. The correct amount is personal and depends on your capital, tolerance and trading rules.
Stop distance affects size
A wider stop generally requires a smaller position to keep the same dollar risk. A tighter stop can allow a larger position while maintaining the same planned risk. This is why position size and stop placement should be considered together.
Why R is useful
R expresses results relative to the chosen risk. If 1R equals $100, then +2R equals +$200 before costs. If another trader defines 1R as $500, the same +2R equals +$1,000. The R result is the same while the dollar outcome changes.
Where NGF fits
NGF maps entry, stop-loss and target levels to support risk planning, but it does not choose an appropriate position size for you. Users remain responsible for their own account risk and execution.
