Is there an account/trade size limit??

Hi all,

This is just something that entered my head last night as i lay there thinking about trading (i do that a lot!!) and i said i'd put it to you guys. is there an upper limit that a spreadbetting firm will allow you to have in your account? currently im with IG Index and unfortunatley i have no such problems with upper limits ect because i'm just not that good....yet!!
what i mean is lets say over time you consistently built up your account and therefore the amount that you were able to risk per trade, lets assume your account hit £100,000 and trading with 5% of your account per trade you'd be placing £5000 per trade, would a normal firm accomadate this or what is one supposed to do if they are good enough to build their account up to these kind of levels?

i read in the paper that one of alan sugars interview guys for the apprentice put a spreadbet on and lost 100s of millions of pounds, so it must have been huge £ per point.

When I was spreadbetting with interactive investor they had an upper limit of £2000 per point.

Wow! so maybe it is possible, like i said its not something thats bothering me right now, just something i was thinking about.

ok so there is such a thing as an upper limit so, thats interesting. i wonder what do all these big shots and super traders that you often hear about do when their account reaches such a size??

open several accounts?

Dma

i presume Dma stands for Direct Market Access. sorry megamuel but im fairly new to all this, with DMA can you place any size order you like? is it true that DMA is not tax free?
