Generally Forex is the market seen as the right vehicle for automated trading today. The reason is the high liquidity and a trading session that spans over almost a week. That is the right hotbed for trading software platforms like MetaTrader and the reason for its existence. There are advantages for autotraders to choose Forex, but there are also reasons to look at the stock market.
Essentially there is one main difference between Forex robots and stock market autotrading. What in Forex is more jumping on trading signals is in the stock market a selection of the right stocks. It is of course possible to swing trade stocks like a futures trader by switching a long position into a short one and that forth and back. But the strength of the stock market is clearly the vast number of stocks. You should take advantage of that!
The easiest way to do so is to have a stock market scanner, a program connected to a realtime database that enables you to either maintain a current group of trading candidates, or to find directly entry signals.
The stock trading is not fully automated with such a system like the above. You still have to manually execute the trading signals or act on your trading group. This has the disadvantage of more work. On the other hand, it gives you more control over the process. The sad truth about Forex robots is that you wake up one morning and the robot has destroyed your trading capital over night. Happy breakfast!
