1) you'll hardly know what the producer of the signal is looking at, so you're flying blind
2) signals are often generated on the M5-M30 making them almost useless unless you're staring at your phone all day waiting for a signal and you happen to catch it as soon as it drops
3) if you look away for a minute, you will miss the "CLOSE NOW!" update and then you'll hit SL
4) often times your spreads will make their signals useless
FOREX is a lot easier then you think
1) trade with the trend
2) trade the H1 and above
3) be patient, let the setups come to you
