Guys, I am very new to automated trading, so please forgive my ignorance. I read about OpenQuant, that it is a good platform to execute orders for an automated trading system. BUT, when I asked a broker (cmsfx) they told me they do not support it. They use VT Trader. I am confused now. 1) Do I need to switch platforms and learn a new programming language every time I switch broker? 2) Do I need to find a list of brokers supporting OpenQuant, and choose one of them?
