Could not resist. Skewed distribution curve is a norm. Perfect Gauss distribution is a very rare occasion. This explains why there is an intraday volatility. For example, average intraday volatility of stocks like KLAC, AMAT, QLGC etc. is around 2.2%. I have done some analisys: If you take daily price moves and for each day you take either (High - Open) or (Open -Low) which ever is greater then divide it by Open you would get daily guaranteed price move (Up or Down). For KLAC, for example, there were no days in the past 400 trading days when this move (up or down) was less than 1.045% (Let' say 1%). So, draw a horizontal line each day that starts from Open price. If Bid is higher than this line go LONG 1000 shares. If it goes to 1% right away quit till the next day. If it did not go there and Ask became lower than your horizontal line then flip your position to go SHORT but this time increase your position by 1/10 of your original position (SHORT 1100 shares). Keep on flipping each time taking new position with the shares equal to 1000*(1.1^n) where "n" is a flip count. If you manage to keep the cost of your flips <= $0.05 per share (let's say $0.01 for your commissions, $0.02 for Bid/Ask spread, and $0.02 for slippage) then your losses each time you flip are only 10% of your profit target of $0.5 per share(1% for KLAC). It ensures you that when the price finally goes to 1% either up or down you will pay for all the flips and you will make 1% return. So, if your intraday leverage is 4:1 on your capital then you have 15 flips to get you to 1% (1.1^15 = 4). So you would make 1% on your actual money. Now, if you look at KLAC data for the past year, the average amount of flips that it took to get to 1% (up or down) was 5.7! So your actual leverage that you used (on average) was 1.7. It makes your capital available for other stocks with the same strategy. Effective return will be equal to appr. 1.97% a day which will give you annualized (compounded) about 100*Original capital. Not bad! And there is no risk! You are always "with the market". If you want to be more sophisticated you can use this strategy on daily/monthly data and write Calls and Puts to pay for the flips. This way you don't even have to increase you shares and your capital usage is better. So, how is this for a random strategy?
