IEX (Investor Exchange) Cloud (https://iexcloud.io/) is a new platform from IEX Group that is separated from the original Exchange site (https://iextrading.com/developer/docs/). This platform provides free access to developers and engineers to the Exchange. It can be used to build high-quality application and services. There is a lot of information in different aspects, and we will try to push our system forward one step at a time. To run the sample programs, go to the IEX Cloud login site (https://www.iexcloud.io/cloud-login#/register) to register a free account. Besides the different URL we will use, it also requires a token generated by the system to send out with the request. The publishable token is the one to be used in the request. A registered user can find a token a https://iexcloud.io/console/tokens as shown in the following screenshot:
