I guess you are asking for the trading software.

My advice is to start with MetaTrader 4. Why? I will explain.

First, this trading app is so called the golden standard in the industry. Almost every broker has included in its offerings. Probably it is the most popular trading app in the same time, used by million of traders worldwide.

Second, it is simple to use, the interface is intuitive and takes a little or no time to get acquainted with.

Third, even tough it it relatively simple to use, it is powerful. Almost all the importan indicators, and other analysis tolls are included.

And finally, this a platform that is suitable for every level of experience. You can find beginners just starting out on their trading journey, or professionals with decades of experience.

Additionally, once you feel comfortable trading with MT4, it will be so easy for you to switch to any other trading app, as I said, it is the golden standard in trading ;)

It's not that big of a choice here. You can pick between MT4 or MT5 which are pretty similar in terms of features and overall UX and UI.

The only thing that is different between them is the number of timeframes and orders. Probably that would be a deciding factor for more seasoned professionals but for you as a newbie it doesn't really matter.

I would recommend starting from MT4 and see how it goes. When you get used to it then switch to MT5.
