Hi, Gary,
Can you confirm you have the user guide? There are also some video tutorials.

You need to first open the drawing tool, select your order type and then submit an order, depending on your settings, a trade might not open. You can start the cBot using cTrader Automate and look in the log tab for any errors.
Can you provide the symbol you are trading, a screenshot of your settings and the steps you are following to submit an order? This will help me find out what is going on.
This tool will only allow a single buy-and-sell trade per chart, you can find more information below.

I ran a test using the tool on 2 charts both with and without the same symbol, I managed to open trades without any issues, if you are using the same symbol you need to change the instance name or it will not work.
Another reason for not opening trades could be trade size, trade setup or account issues, the cBot log should tell you what's wrong.
