Focus on your trade, not on your profit or loss
Rather than wasting valuable forex trading time continually computing your profit and loss on a trade, focus instead on executing the trade plan that you had devised for it properly and with the required discipline. You can also spend time on developing and executing a suitable follow up strategy once the market has moved after the trade has been initiated. The precise accounting for a trade’s profit or loss can always be done after the trade has been closed out. Also, some popular forex trading platforms like Meta Trader 4 will continuously mark each of your outstanding forex positions to the market so that you can get an instantaneous sense of how well each one of your open trades is performing without having to do it manually.
