good on you for taking action. tbh mate, being good or having a A* in maths is a myth, sure you will need to be able to do the odd sums and multiply, but it is all basic stuff, trading is about developing the attitude and discipline to follow through on your trading plan and to learn to be able to dissect information quickly and effectively as well as making a decision without hesitation and most importantly having conviction in your trade.
different places will have different entry requirements, but generally if you show a place a PnL of consistent profits during a 1year period do you really think they would be bothered about you being good at maths?thb mate,my maths is average, yeah i know my %, multiplies etc but anything deeper such as algebra and quantum physics then you've lost me, not that you need that anyway but you get my point.
im on a pan euro desk covering equities using a top down macro view for choosing stocks. anyways, i dont come on here much these days, just get replies in my email and i try to reply when i can so im not ignoring people........had to get that one in!
anyway, good luck........
