Map of Port Berge Vaovao on I have seen so many traders in my own room and heard about many others that have ended their careers because of that one stock that had to come back but never did. Eventually, the pain of loss became so great or worse, yet a margin call came, and they had to quit trading before they ever had a chance to see if they really had the abilities to become good traders. It is said that 70-percent of daytraders fail. A percentage of this failure rate is due to the inability to keep a tight stop loss. It only takes one bad trade to wipe out a portfolio. Don’t let this happen to you. A stop loss should never be seen as a negative thing as long as it is taken in the right steps of the trading process. Map of Port Berge Vaovao 2016.
