How to Load CSV Market Data Into cTrader

Learn how to load historical market data into the cTrader trading platform to test your automated trading systems (ATS) over a longer timeframe to capture as many market conditions as possible. The data that is provided by your broker is loaded into the cTrader trading platform when you backtest your automated trading systems (ATS) with historical market data. 

Before backtesting, you will have the option to choose data source - Either one-minute trend bars from a broker server or one-minute trend bars from a CSV file on your local disk. If you choose to use a CSV file you will need to specify its location, after which cAlgo will analyze the file and adjust minimum and maximum available dates for backtesting.

 

Step 1.

The cTrader platform has a module for backtesting and to get started you first need to make sure you are looking at the automated trading screen, just click on the button shown in green on the left-hand side of the screen to open it.

Also, select your Spread as a fixed value, just copy the current live value by clicking the green button, be careful, if the markets are closed this value can be incorrect and very high, just look it up ion your broker's website instead.

 

How to Check If the Data Loaded Correctly?

To check if the CSV data has loaded into cTrader correctly you can look at the start and end dates as shown below and you should see the sliders at each end of the control, in the example below it shows data from 11.11.2012 - 17.09.2014
