Save your money

This app is garbage. I’ve been trading for 10 years and there are so many flaws with this I don’t know where to start. The biggest flaw is your trades only execute during a 15 minute window at the very end of the day. We all know most of the action happens during the morning. Not being able to trade during optimal time period to buy lows or sell highs is killing this app.

Misleading historical charts

This a fraud. The charts are meant to show what your money would turn into if you invested 10k in the past. But in reality the buy and sell orders never get filled at lower prices than the chart suggests and you will consistently under perform or even lose more and more money compared to what the line chart suggests.

Please save yourself.

Response from developer

Hi there! We’re sorry to hear about your experience. The chart displays hypothetical historical performance and is intended for informational purposes only. It does not represent actual investment results or guarantee that trades would have been executed at the prices shown. If you have any further questions we encourage you to please contact our support team so we can review your specific account and trades. Best!

Interesting Concept the App is poorly developed.

I like the concept. This review is more about the app than the idea. The login takes forever and often times out. There doesn’t seem to be any documentation or knowledge base. They reference sharpe ratio or calmer ratio but don’t seem to show definitions or formulas. The Home Screen is lacking, you get a chart of your investment and that’s it. Look at other brokerage apps and get a little inspiration.

Avoid - skips trades routinely

Traded less than 10 times over the course of a month after transferring $30k into it. 2 times composer did not execute the change in the next change window (which is already a lag since it only happens at the end of the day). It cost me $100s. The lack of control you have over trade timing is genuinely concerning. Support is terrible and took days to reply after confirming they skipped trades. I immediately liquidated my funds and transferred out. I recommend you stay away. Too many other options out there to deal with this trash.

Casual investor

I don’t gamble often but when I do it’s poker not day trading. (More fun). Composer offers a place for me where I (the casual long investor) can do copycat or easily utilize AI with my own parameters, instead of institutional research departments and the fees associated with managed accounts. I m trying it for a bit to see how it goes. Lots of etf going on by AI here.

FAQ

What does the Composer: AI Trading app do?

This app uses artificial intelligence to help users automate their stock and ETF trading. It allows you to create custom trading strategies by describing your ideas in plain English, backtest their historical performance, and then automate their execution. You can also mix automated strategies with direct, instant trades.

How can AI help me trade stocks with this app?

The AI can generate custom trading strategies based on your specific ideas and preferences, or it can surface high-performing strategies from a community of users. This eliminates the need for manual strategy creation or coding, making automated trading more accessible.

What are the costs associated with using this app?

The app offers a 14-day free trial for its automated trading features. Following the trial, subscription plans start at $32 per month when billed annually. Specific details on commissions and fees can be found on their website.

Is my money safe when using this trading app?

Yes, the app employs best-in-class security measures including two-factor authentication and bank-level encryption. Composer Securities is also a member of SIPC, which protects customer securities up to $500,000. However, SIPC does not protect against market losses.

Can I start trading with a small amount of money?

Yes, you can begin automated trading with as little as $50. The platform allows your chosen strategies to trade automatically based on the rules you set, and you can pause, edit, or liquidate your positions at any time.
