I hope you can take good advice offered in this thread. Most people can't live on trading from own funds. Professional traders usually live off others' funds and risks, and that is a game in itself of which retailers know very little.
There's a real risk that if you go full-time, you won't make the transition. As you've probably discovered, trading more doesn't necessarily equate to more profits, rather the contrary. Also, if you rely on some mechanics in the market place, these things tend to change over time, especially if there's no sound reason for them to be there. Then there's the emotional baggage if you rely on living on trading profits, withdrawing living expenses from trading account = not good.
So if you're currently making it, welcome to the rest of your life! What do you want to do with it, stay uneducated? Or play with life, see where it can take you, while not betting all on just one stallion, but diversifying?
Wtf is so glorious about being full-time trader anyways? It's a shitty life sitting glued in front of a screen frantically clicking, very very stressful. So doing it part-time is actually a safer bet. However, only you can conclude, since it's your life and depends on what you enjoy and find meaningful.
Kudos for staying green for so many trades and years though.
