Stock market screener programs are now used by millions of traders around the world to spot high probability trading opportunities and invest accordingly. If you are unfamiliar with this technology or are interested in getting into the stock market but don't have the time to put towards it, here are the top three reasons traders use a stock market screener which you should be familiar with.

1 - Arguably the leading cause for why traders lose money in the stock market is because they can't control their emotions. It's essential to have an exit strategy and follow through on it in the market. As important as this is, however, many traders find it difficult to bring themselves to get out of a trade in certain situations. An example of this is such as when they are invested in a stock which has long performed well for them historically and they wait for a reversal, all the while hemorrhaging profits. Using a stock picker, all of the analytical work is done for you so that you know exactly where to trade and where to set your stop loss at even so that you can invest and forget.

2 - Secondly, a stock market screener is the most reliable way to trade ahead of the curve. This is due in small part to the fact that emotions don't factor into your trades, but the picks behind the stock picker are based on mathematical algorithms and take the full spectrum of the market into account to find overlaps in behavior to find current stocks which are likely to perform like stocks of the past, simply based on the market conditions surrounding them.

3 - Finally, analytics are arguably the most time-consuming aspect of investing. With a stock market screener plucking high probability picks for you, you can simply invest accordingly without having the time or experience to devote towards the market or having to outsource the trading work to a full service broker.
