I can tell you the last trade thing. You see, when you are ttrading without a stoploss, and ( or ) without any exit criteria , there will be some positions , which just wont be profitable. They are summed up in the last trade. So they were opened, but never got to the 100 pips, so trailing stop could not been enabled. Possible solutions:
-Add a stop loss
-Add some closing position criteria ( for example , macd is crossing back, or stochastic is closing back and so on )
- Lower the trailing stop level, from say 100 pips to 50 pips.
I would prefer a combination of an exit criteria and reduced trailing stop. Only to get the best exit criteria you have to do some research. Let us know how it goes.
