Actually Jav, it's not the size of the account at all, it's the percentage you risk.
If you risk only 2% of your account, it doesn't matter if it's 2% of $500 or 2% of $10,000. As long as the risk to reward ratio is the same, you'll come out ahead as long as you don't go in too heavy on any one trade.
If I'm playing short term charts like the 5 minute I usually go in heavier. But on the longer term charts like the 4 hour and daily, I go in much lighter and cost average. Take USD/CHF for example. I know from the chart setup on the daily that it's getting ready to bottom soon. No way to find an exact bottom but I know that as long as I go long during the 5th wave sequence, it will eventually turn around and go back up.
So what I do is average in every 100 pips or so when playing the bigger time frames. Since I don't put down a large percentage of my account on any one trade, I'm not in danger of blowing out the account and I still have plenty of capital to trade other pairs if I want to in the shorter time frames while the larger time frame trade is developing.
Money management is absolutely essential next to good technicals. They go together like peanut butter and jelly. :-)
