Composer is by far the best product I’ve come across in a long time.
It’s an absolute gamechanger.
I've been doing this for 35 years and have never seen a tool like this. Not even my Bloomberg!
Composer gives traders and investors at all levels an easy and intuitive way to develop, trade and automate their investment strategies.
Composer opens up to anyone the same level (or better) of tools that top quantitative hedge funds hire armies of PhDs and computer scientists to build internally.
Wow, @ComposerTrade makes it ridiculously simple to create automated trading strategies
Most automations require you to understand detailed spreadsheets and unique coding languages, the learning curve is often intense with these platforms. That’s not the case at all with Composer.
