Web-based trading platforms are commonly offered by CFD & forex brokers, including by many brokers that offer stock CFDs. In general, these platforms make the trading experience easy and intuitive, offer dynamic charts, and automatically saves all work that is done in the cloud. This also makes it much easier to access the same trading platform with many different devices.
Although some traders and brokerage companies consider web platforms to be the future of trading platforms, downloadable and more traditional trading platforms are still very popular. Among other things, traders like the traditional platforms for the ability to code and create custom technical indicators and trading strategies.
