By profitable do you mean "positive expectancy"? If so the Arcsine Law will do the trick. Ninna

4square database is worth much more than $125M. It has potential to kick Google's ass provided it doesn't get bought.

What's the inflation rate on the Rupee? I would start with basic trend-following. With strong MM it will give you some time to figure out more sophisticated strategies.

You made several assumptions. At least one is wrong: you assume the less efficient the market the better. It is exactly the opposite. The most efficient market is the easiest to trade because it is the most predictable.

It is very easy to automate. The problem is you're then able to run some statistical tests on your "strategy". And you quickly realize that you have no edge and that your (hypothetical) success so far is due to luck. Talk about a bad day...

Everyone's telling you every minute how to live. Mostly in subtle ways you can't even comprehend. Leave America, get a different perspective. Then you might understand to what extend your thoughts are being manipulated. You'll also understand that you can't fight it.

From memory, the market returned a bit more than 13% p.y. since 1900. That's about 9% real return. Nevertheless the variance was huge.

You can do the same by buying currencies that pay high interest rates. It still doesn't protect you from the depreciation of the underlying. If you're looking at long timeframes (25 yrs+) you might survive drawdowns with small leverage but you'll get huge variance in your returns. And it's...

No pattern in the price/time plane has any statistical edge. You're wasting your time and your money.

IQ doesn't matter if you're smart enough to hire people that have theirs higher than yours! :)

No. Do you really think you can beat the market with a 2-4 week course while dozens of phd's dedicate their life to the task and still fail? I you don't want a professional to manage it for you I would buy the SPX (if you don't need the money) or bonds (if you might need it). Keep a...

Advise books on patterns: don't read them.

It depends on what you do. If you use an automated strategy with a well defined and stable distribution of returns you might need fixed stoplosses when you enter your trade in order to define your maximum risk (ex. 1% of capital). This then allows you to provide statistical guarantees based...

It might work in some countries if you have time (i.e. 25 years+) to wait during drawdowns. In my country we don't have any tax on capital gains. However dividends are taxed 35%. :)

I don't think this is the main problem. For instance it's an issue that doesn't apply to turkish lira. Depreciation of the underlying asset is the problem.

Why isn't anyone buying turkish lira??! They pay 15%+ yearly interest! That's better than 99.9% of funds.

There's no right way to draw it. Many ways will work. This is, again, because prices are random.

They work because prices are random.

What's 3.8% compared to the millions of people that are currently dying down your street?

I've seen a lot of start-up fail within the first 3 years. For about 80% of them, it was due to overoptimism concerning cash flow. If they can show that their primary concern is controlling and monitoring cash flow they won't have issues rising money anywhere (banks, venture capitalists...
