There are pros and cons of both self-trading and using a broker. The main advantage of self-trading is that you have complete control over your trades and can make decisions based on your analysis. However, this also means that you are solely responsible for any losses that you may incur. Using a broker gives you access to professional advice and guidance, which can be helpful if you are new to trading or do not have the time to do your research. However, you will likely have to pay fees for this service, and you may not always agree with the decisions that your broker makes on your behalf.
If you do not want to go for self-trading because of the fear of Risk, then you must use the trading simulator to test and make your strategy; once you are confident with your simulated trades, you can go for the real market.
