Right now, there are a lot of free signals services online which allow traders to trade profitably without having to pay a dime.

Trading signals are simply a set of algorithmic results generated by software which relies on various technical indicators, such as MACD, Relative Strength Index, Bollinger Bands, and Moving Averages, among other tools. Some also do employ the use of custom-made trading signals and candlestick patterns.

Ideally, these are the same tools that people use to trade on a case-by-case basis, but in this situation, everything is delivered on a plate for the trader to decide on whether or not to implement the signals received.

This also implies that traders with little or no experience/knowledge in online trading can reasonably rely on such signals to make winning trades in the market. 

Online trading is increasingly becoming common among people as they search for alternative measures of making money online. Forex trading, in particular, has been the dominant form of online trading for decades now, but it has existed in the market for thousands of years.

Over the last few decades, new forms of trading have entered the fray including Contracts for Differences (CFD) trading, Spread Betting, BitCoin trading, and of course, Binary Options.

Software developers in conjunction with expert traders have been working on trading tools to help in making the process of picking trades simpler. As you know, online trading depends a lot on the timeliness of trade execution. Delaying your execution by a single minute could result in losses rather than profits.

Now, while forex trading platforms like the MetaTrader 4 and CTrader do allow traders to code various programs for picking trades, in binary options those opportunities are limited. A few have tried to come up with MT4 based binary options signals, but the best option still remains the web-based signals.
