Coaster Forex Telegram chanel is a scammer who manages accounts with MT4. With his Telegram chanel there are no any real trade demonstrated, just lucky charts to involve you.
At the real account trades are opened without any system and no risk management rules at all. Coaster Forex promisses a unique trading technic, but in reality he can not identify the market direction. No TA rules are aplied.
This scammer trades with IC Markets at raw spread accounts with great commissions. I think he has a link with this broker.
