Tiny - a few hundred. I think it was with Finspreads, or some similar third-rate bucket shop.
Spot forex through a spread bet company. Can't get much worse really.
Didn't blow up as such, just lost a little (in cash terms, although as a percentage of the opening balance it would have been fairly significant), stopped, rethought things, moved on.
IG, in the days when spreads on indices and FX were five to ten times what they are now, and the internet was so slow that prices were probably a few minutes old by the time they reached the screen. Lost my £250 pot pretty quickly, then discovered binary bets and lost the same again even more quickly.
Lesson learnt, and far more cheaply than signing up for a trading course.
And what was the lesson you learned?
You really want to know... lost 10k account back in 2008. Was new and naive and put it down to lack of experience....then since then probably blow over 10 accounts of 300-500 each...put that down to being under capitalized....
Recently just had my worst yet...lost 15k account by over leveraging, adding to losers and being stubborn.
Giving up for good now, I simply can't control the gambler in me!!
