I made the switch to fulltime trading back in July when i finished college...
Started with £759 (all the money i had in the world), i went from that to £5,690 in 2months, all at just £1 per tick, and with a 12ticks spread per trade. (UK spread betting firm).
I then withdrew down to £2,000 at end of august as i moved into a luxury new apartment and paid rent inadvance + funiture and stuff,
and then since mid september whne i restarted i gone form 2k to over £8,000 now, all at just £2 t £3 per tick, and still scapling with that 12ticks spread! lol
Every single day has been written in my online traidng journal, daily explanations on what trades im gna make, and screen shot statements posted to prove its all real.
So you dont need anywhere near 300,000quid to make a lviing traidng!!! LOL
It helps if yo do, since then if you go months n months earning zero or losing money or just not earnng over 1,000quid you dont endup homeless or anything.... lol
But you get £3,000 and start traidng £1 t £2 tick, and thats should be enough to start from.
