A Signal Service provides alerts on trading opportunities. For example, a professional trader sits at his desk, trading his account (or his company or hedge fund account). Whenever the trader enters the market, he also sends an alert to his subscribers, giving them the opportunity to enter the same trades as him. Some service also provide an automated robot, sometimes called a Trade Copier or a Trade Cloner. This robot will execute the same trade on the client's account, so clients don't need to actually go to their computer and execute the signals manually. Such service is "Vladimir's Forex Signals & Mentoring".
One note of caution, though: The phenomenon of ‘curve fitting’ means many of these EAs don’t work over time because while they explain past performance and past data in the market, they often lack predictive power. In other words, any curve – or any financial result in the market – can be explained by a mathematical formula. That doesn’t mean the formula or algorithm is capable of predicting the future.
Your bot will also have to import market data in some way, possibly in “real time” (with extremely low delay), if your trading algorithm in any way must react to what’s happening right now in the markets. If trading decisions are based more on fundamental factors and are just waiting for the “right price”, getting market data with millisecond delay might not be essential.
Company Policies and History: As part of every investors due diligence process, steps to help ensure account security should include verifying a firm’s regulatory licenses and its legal obligations in safeguarding client monies. It's also important to review the customer agreements, read up on the company's history, and make sure their primary offices are located in a well-respected country, if not your own.
Automated trading software can be a great way for beginners to observe how a professional traderapproaches the market.This gets back to emotional issues, the plague of all forex currency trading beginners. If you select wisely, and only place the robot on a demo account or small live account, you can sit back and “see how it should be done” at your leisure.
Finding a strategy or system that works is not the hard bit, there are plenty of systems and methods on these very boards. The difficulty is configuring them to be consistent and to continually adapt them to keep up with the market. The other trick is not getting misled by short term results or backtests. Any truly successful strategy should be able to work through bull, bear and sideways markets. Sure they might not always make money but they should be minimising losses or going flat not completely falling apart, the latter being a sure sign of over fitting.

The BATS exchange is frequently used in actively traded stocks so a transaction will likely go through on BATS at each price level the stock moves to. The charts turn out to be quite accurate in this respect. In lower volume stocks where fewer transactions occur, a transaction might not go through on BATS at each price level where a transaction on another electronic exchange takes place. In this case, you're missing pieces of information on your free charts that paid real-time charts would show. 

Although not all programs on the Internet operate well, there's a good chance you'll find something useful, perhaps even the best Forex auto trading software.

In fact, the best software publishers will undoubtedly provide authenticated trading history results in order to show the effectiveness of the programs they are offering. The golden rule is to understand that the past performance is not a warranty of positive future results.
