Trader’s Tech #12 – Indicators, Scripts and EAs

Yesterday, I promised we’d talk more about Forex trading software. Our discussion will focus primarily on the Metatrader 4 (MT4) platform for ease of explanation. We’ll discuss other platforms in future articles.

Let’s start with giving you an idea of what these three things are:


An indicator is a line or other group of markings on a chart that assists you in analyzing price action. Indicators often take the form of a line such as a moving average that is superimposed on the price action chart that allows you to see where the price action is in relation to the indicator. You may also see indicators that have their own sub-windows (such as the Stochastic or MACD indicators) and their own scales. These indicators may have multiple lines that can be used to indicate certain market conditions. Other indicators may manifest in the form of marks on the price action that show potential reversal levels or prior highs/lows. Indicators don’t actually execute trades, they just give you additional market information over and above the pure price action. These indicators can show you certain calculated results of price action or other indicators – or may even bring in data from other pairs or markets to help you identify your highest probability trades.  When using indicators, remember that more is not necessarily more. You can have too many indicators that will just result in confusion.

Here is an example of an indicator that has it’s own sub-window, allowing you to compare the lines to it’s own scale or to look for crossovers of multiple lines. Sometimes, the indicator is a simple histogram indicating momentum or volume.




Well, that’s all we have time for today. Tomorrow we’ll go into scripts and how they are used.  Thanks for your attention!
