wannabe,
i remember being in your shoes. Whats your money management system, for example after you lose x% of your account do you downsize until you get x% back etc? remember, if you lose 1/2 you have to double your money just to get to breakeven. Its a question of tuition, how much do you want to pay. Why not looking at as having the RIGHT to trade? You haven't EARNED the right to trade size because you aren't profitable yet. Kinda like getting your degree in college you had to do all the classes first..
also the problem with concentrating all your size in 1 positioin is what if you are short and it comes out that the company is being acquired for 2x the price you were short at?
statistically, big traders and smaller traders never make money. Small traders never risk enough to make anything and big traders usually make a ton till that '1' event happens and blows up everything.
Consider medium sized bets.
also, something that might help. You either need a HIGH win ratio or good reward/risk. For example, since I swing trade I look for 1:5 odds and I'm usually right at least 40% time (choppy market) and 70-80% in trending markets. Either way I make money, just a question of how fast.
If you are intraday scalping, the only successful ones I've seen are ones with high win loss ratio and inverted risk reward ratio. Ie they are right 80% of the tiem but their losses are 2x their wins. So, in that case they are just right very often.
Anyway, please consider these two things they helped me ALOT and don't want you tohave to learn these the hard way!
This is just my opinion so best of luck.
