The Lien Schlossberg forex trading signal service hasn't worked out well so far.  It isn't so much the losses they have incurred as much as the inability to act in an expedient manner to execute a trade based on their signal.  Here are a couple of reasons why it hasn't worked out for me:

1. I lost a little bit of confidence in them last week.  They made a couple of trades last week that I felt were impulse based on previous losses.  This is strictly my opinion because there is no way I could actually prove this.  I could be totally off base.  They did state in a weekly recap email that they made "boneheaded" calls.
2. As I've stated before, their trade calls have to be followed very closely.  When I get a text message or email from them, I must execute the trade right then and there.  They have sent out trade calls during many different times so I've had to be on my toes.  I can't always be in front of a computer with my trade platform open though so this has not been easy.  For instance, yesterday I was in a USD/CAD trade that had a set profit target and stop loss.  They jumped in at 7:15 am to tell me to get out of the trade.  I couldn't because I was in transit.  Instead of making a tiny profit, I lost 4 pips.  This is totally acceptable to me considering the ever changing market conditions so this is not a knock on them.  This is more a question of whether these type of trade calls fit my schedule. 
3. I haven't received the trade calls via text message because they failed to be delivered.  I don't have real-time access to my email all of the time but I do to my phone.   They finally stated after I had asked them a couple of times that Verizon was failing to deliver some of their text messages due to overload.  It seems like they may have addressed this issue.  I'll have to wait and see.
