LSE:EXPN You have to understand that even if most of the time your trade turns against you, when the trend moves in your favour, you have to manage your position disciplinarily. Look in this trade as in the first operation we have succeeded in doubling the value of our position realizing exactly a good 200% on the allocated, and in the second operation we are still long currently with a profit not yet realized of 1000% and protected in case the trend begins a reversal or we suffered a heavy retracement.
If these were my only two trades to profit in the last ten, so would be the situation of my profits/losses: 2 profit trades = (1*200%) + (1*1000%) - 8 trades at a loss = 8*100% = 1200% - 800% = 400% on allocated capital
