Would you download an trading tool that is google chrome extension? I know that some people kinda afraid that it will be a scam and somehow their information will get stollen.
What will make you gain confidence and download it? what does the company need to have/show to you in order to gain your trust?
Why would you need this kind of tool? Nothing on the internet can guess the results of trading. It is only for you to find out everything and not relying on some script kiddies tools. Some of these tools nowadays are having a malware that could read or send any files from your browser or computer. Don't trust any of these if you want your computer to be malware free. Anyway, some antivirus could easily detect any malware that's being planted on your computer.
It's better safe than sorry.
