How I Measure
For the record (does such a thing exist?!?) I measure the profit / loss in the following way for a long trade:
profit/loss = (sell price – buy price) / buy price x 100%
Note – I do not take into account any transaction costs such as brokerage, margin interest or otherwise in this diary. My real trading does take that into account as they all hurt when my actual losses are bigger than I calculate and my profits are similarly less after the broker relinqueshes me of those fees!!
So – if you were to catch the exact same trades as I write up, you will not get the reported returns… which is not to say if enter or exit better you wont beat my returns!
