1 - STAY AWAY from ( the magical combination of 3 , 4 , 5 indicators ) that will bring you a lot of money , cause that's BS .. they are ALL lagging ...
2 - STAY AWAY from Robots .. they can't work at anytime , at any movement of market ( trending, going sideways , after a news ..) . the real algorithm robots are in the big trading floors of the biggest banks and hedge funds , monitored 24/7 by so they will not screw up ... not an EA that coasts 500 or 1000 $ !
3 - Try always to take a zoom out ( depending on what type of trader you are ) ... try to know about the story of that pair through out the price action , so you can build later '' probabilities '' : what ever the price goes , you know what u should do, and how much you gonna risk.
4 - Don't forget the fundamental part of the trade ( don't relay on it , but take it in consideration : checking all the time
5 - Risk management is crucial trade only small ... risk only 0.5 to 2 % max.
6 - Begin only with 3 pairs .. 5 as a max .
7 - Stay away from those who claims to be '' gurus '' , they are only salesmen and poor teachers ... Learn from someone who already '' made it '' and now look for another goal which is being a well known teacher ..
