Are there any fees for changing trading platforms?

At AMP Futures, you can switch between trading platforms that use the same data feed without any extra fees.

For example, if you're using the CQG data feed, you can freely switch among platforms connected to CQG. The same applies to platforms connected to Rithmic.

By default, all available trading platforms connected to each data feed are enabled by default.

You can see all the different trading platforms per data-feed here:  https://www.ampfutures.com/trading-platform

However, if you decide to switch to a different data feed (e.g., from CQG to Rithmic), this will incur additional fees. Each data feed reports your market data usage to the exchanges separately.

Therefore, changing data feeds within the same month means you will be charged for market data on both feeds for that month.
