You are not a trader until you stop meddling with you stop loss pushing further and in the long run sustain losses.
I'd couch this concept differently, in the form of an unfinished phrase... You are not a real trader until... You have traded with real money. At that point, you have become a "real" trader. Hit or miss, you've entered the lion's den at that point, and you're in it for "the real".
You are not a trader until you are patient enough with your trades and have overcome the grief of your past losses.
You are not a trader until you can accept that you can be wrong and the market is always right! Look at the mirror at your biggest enemy. It is you!
you are not a trader until you realise profit and loss are a part of being a trader. once you invest in something there's a 50-50 chance, there's no sure shot answer in a trade.
What is happening now after 10 years of a bull market is that every young pipsqueak thinks they know what they are doing. You're not a trader until you lose some money. As long as you think you are a genius who cannot lose, you're still waiting to become a trader. So, I heartily support the position above: you've got to trade through a really bad market to make it into the club.
You are not a true trader until you lose in the market. I know that some people get heart-broken when they face some losses but they should think of losses as learning curves. These losses will help them grow as mature and experienced traders. So, losses are not that bad of a thing.
