Help: Calculation of risk and return

Hi, everyone, hope you just had a Merry Christmas. Could somebody help me how to calculate the risk and return of a trade.

Suppose my account's currency is GBP. Now I bought ABC-XYZ at price a1 with Stop loss a2 and Take profit a3. The current price of GBP against ABC is b1. Suppose when ABC-XYZ touches stop loss a2, the price of GBP against ABC changed to b2; while when ABC-XYZ touches take profit a3, the price of GBP against ABC changed to b3. My question is, what my risk and my return of this trade?

Many thanks for your help.
