After a decade+ bull run, the market is changing. Is your portfolio?
Picking stocks is difficult.
The chart doesn’t only go up – it can also go down.
Protecting your money in the face of inflation and economic uncertainty requires more than a robo-advisor and a prayer.
You deserve a smarter option that responds to market movements without endless hours of research and screen time.

Capture upside with downside protection
Composer can move your portfolio into its best performers when the market is doing well, and hedge risk during volatility.

UI element showing specified weighting: 70% to ICLN, 20% to FSLR and 10% to TSLA

Apply weighting

Custom weight, inverse volatility, market cap or balance equally.

UI element showing conditional statement: If the current price of SPY is greater than the 200d moving average of price of SPY, buy SPY, else, buy BND

If this, then that

Add conditionals to control the flow of logic.

UI element showing an example of a filter: sort these by their 90-day cumulative return and select the top 3: SQ, SPOT, NFLX, AAPL, SHOP, TWLO

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

@meetnaren

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.
