Hello Adam,
yes, there are such EAs and scripts for trailing the SL that you can apply to any Expert Advisor. This will be the easiest way for you if you want to put different SL and TP. Keep in mind that as Travis said, it will change your backtest which means that you will not have the same performance from what you saw in EA Studio when generating the strategies.
Regarding the first picture, again I say you are looking at different EAs.
Look at the right up corner where is the smiley face and the magic number of the EA( I place a big white arrow). It is a different number from what you see in the code. Simply you look at different EAs with different SL and TP.
The function of the SL and TP works just fine, all bugs and mistakes were fixed long ago.
However, if you still can not see it properly, let me know and I can have a quick skype look at your screen and make it clearer for you.
Kind regards,
Petko A
