Traders that are new to trading the Nadex 5 minute binaries typically test their strategies in the demo environment and then maybe shocked to find that they cannot always use the same strategy in the live environment. Quite often this is the case with trading strategies that are based on deep in the money binary options. This is also why we recommend that you compare the live and demo environments while testing your strategy. It is also why we receive numerous questions regarding the differences between demo and live environments.
First, if you are testing a strategy for trading Nadex 5 minute binaries, you should have both a demo account and live account. You can open a live account with as little as $250. This will allow you to compare both by opening your demo account in one browser (ie Google Chrome) and your live account in another browser (ie Mozilla). Now you can place the browser windows side by side and compare your demo entry with the price and strikes in your live account.
Second, you will need to test both environments during the same period. For example, during London you may find that the prices, strikes and number of contracts offered are almost identical but, then when the US session begins, everything is different between the two accounts.
