Top 3 signals

From a Friday to Monday, top 3 signal, 2 vanished, 1 badly hurt.
Actually it not surprised me at all.
 If you at this place more than 5 yrs, you will know this happened again and again. 
People don't know how to trade, what to expect, fond to martingale, this is the destination, sooner or later. 
Every trade must have SL at least, this is the rule No.1 of trading, hope people can understand. 
I am starting and before to put the money I am reading to understand more or less how to trade and use this software and signals. This is pretty complicated for me, I supposed that you reffer to the minimum quality of the company to invest, for example the use SL.
