Statistical modeling and forex trading

Key points

• Trading often gives traders a more accurate idea of their expected return
• Price extremes can be a good place to either go with or against the trend
• Using stop-loss and take-profit orders can help manage expectations around risk and reward

As traders open and close positions, they accumulate data that can be used to manage future trades. Averaging the profits and losses over time provides an expected return per trade in a single number. Ideally, this expected value is positive, and further analysis can help increase returns.

Risk / Reward example

The risk-reward ratio (R/R ratio) is a way of assessing the expected return on a trade per unit of risk. As a trader, you’d typically use the monetary amount you stand to lose as the risk input, and your expected profit as the reward. So, if you risk $100 and expect to make $300, your R/R ratio will be 1:3, or 0.33.

Let’s look at a theoretical trading example. Say you expect a US dollar pair to appreciate 100 pips, so you open a 1 lot long position and set a stop-loss order to automatically close your trade if the price drops 40 pips.

Assuming the stop-loss order fills in full at the set price level, the maximum amount you stand to lose is $10 per pip x 40 pips = $400

Your expected return is $10 per pip x 100 pips = $1000

Your R/R ratio is 1:4, or 0.4
