Theo by (from the minds behind and is a new, innovative way for Traders to keep in-touch with their Trading Positions around-the-clock. During the regular trading session Theo will value your account in the traditional way using symbol specific market data for each Trading Position. After-hours and Overnight, Theo takes the current Futures quote (/ES) and uses it to calculate the theoretical, beta-adjusted underlying price as well as Position Value.

Theo currently supports TD Ameritrade brokerage accounts via their API and it's capabilities, but look for more Brokers to be supported in the near future. In addition to the Theoretical Position data, Theo will also display the Theoretical Last Price, and the corresponding Beta value for each symbol. Market data may be delayed due to Exchange Restrictions and Entitlements.

Access to your Account data can provided securely by enabling Touch ID to store your Account Credentials, encrypted, on your phone. Theo is designed to not keep any information it does not need to function, and all data it does keep is encrypted.

If you've ever wondered what your Brokerage Account is doing when the Markets rally overnight, then this is the App for you.

Customer Reviews

Great solution from dough!

I have really loved apps for viewing my portfolio positions in aggregate, but options have always been poorly calculated. This app solves that problem and allows active, up-to-date PnL on your strategies.

Bonus: while most aggregate apps are dead after hours and weekends, Theo gives those of us with "little changing numbers" addictions something to stare at.

Great job outta you, Johnny.

More tools from the Dough Folks!

Look, I'm pleased they are pushing out more content and changing the old paradigms of investing. Theo is another tool in the bag that will allow me to make better decisions. Seeing the "theo" of my portfolio overnight is something I never envisioned until now.

Thanks Dough Team!


Great App! Allows quick insight into your TD Ameritrade brokerage accounts. Very simple and clean interface for quick reference anytime.
