The GDAX price indicator collects current cryptocurrency prices from the GDAX exchange (www.gdax.com) and displays them on an MT4/MT5 chart, for comparison against your broker's prices.

The indicator can display the following GDAX prices: BTC/USD, LTC/USD, ETH/USD, BTC/EUR, LTC/EUR, ETH/EUR, BTC/GBP, LTC/BTC, ETH/BTC.

The following example shows the GDAX spread for BTC/USD, including charges, lying entirely outside the broker's spread (GDAX in blue; MT4 broker in orange):

2.1Installing the indicator

The www.fxblue.com website provides an installer which automatically adds all the indicator's files into your selected copy(ies) of MT4/5. After running the installer you need to update the Navigator in MT4/5, either by restarting MT4/5 or by right-clicking over Indicators in the Navigator and choosing Refresh.

Please note: the indicator requires v4 of the Microsoft .NET framework. If this is not already installed on your computer, you can download it from the following address:


2.2Compulsory indicator parameters

You need to turn on the "Allow DLL imports" setting for the indicator, and enter your FX Blue username and password.

2.2.1"Allow DLL imports"

You need to turn on the "Allow DLL imports" setting, on the Common tab when adding the indicator to a chart.

Please note: changing the setting in Tools / Options / Expert Advisors does not affect any EAs or indicators which are already running. This setting controls the default which is used when you next add an EA or indicator to a chart.

2.2.2FX Blue username and password

You need to enter your FX Blue username and password in the settings for the indicator:

2.3Choosing the GDAX symbol to display

You need to choose which symbol from GDAX to display, from the drop-down list of options, to match the chart in MT4.

2.4Colours and display style for GDAX spread

You can choose the colour for the display of the GDAX spread, and whether to show ask and bid lines or a filled rectangle.

2.5Widening the GDAX spread

GDAX has charges for placing market orders, which widen the effective spread (e.g. https://www.gdax.com/fees/BTC-USD)

You can include these in the display by entering a value such as 0.25 for the spread-widening. This will lower the bid price and raise the ask price by that percentage.

2.6Displaying the MT4/5 spread

You can choose to display the MT4/5 spread as a filled rectangle, for easier comparison against the GDAX spread. If you turn this off, then you can instead use the chart settings in MT4/5 to display a line for the ask price as well as the bid price.
