Update on FXLeaders and Live-Forex-Signals.com:
FXLeaders is a "human" signal provider. They do have profitable trades so you can use their signals for confirmation.
Live-Forex-Signals.com, however, is a robot, I think. There are profitable trades but I still need to figure it out WHY the robot (?) opens a trade. It seems random. Be careful 'tho, the numbers are a little rigged to show more profit/pips. If you only follow the buy/sell signals then be sure to set the TP a little closer or monitor your trade. Most signals are OK I think.
Also, only use TradingView signals for confirmation because the computer never knows when the trend might reverse etc...
That's it for now.
Still testing these. And remember, always follow your strategy. Use signals for very final confirmation. Never blame yourself or the signal.
