Profits and losses are made based on PRICE not on volume. With the entryPRICE and the exitPRICE you can calculate your profits or losses.
If there is a reaction it will be visible in the price, so why bother about volume? Volume does not say at all if buyers/sellers want to pay more or less. Price tells you that. Volume is only important to see if you can take or dump the volume you want to trade. Never trade anything with low volume.
