Here's how to use JPMorgan's new free stock-trading platform that the bank hopes can take on upstarts like Robinhood

You can initiate a trade right from the home screen, or dive into any of your accounts for more options and information.

Unfortunately this is where simplicity goes by the wayside. After the initial deposit, there's no button from inside the brokerage account page to make another cash deposit.

To add more cash to your account (beyond the initial funding), you'll have to head back to the main screen. After tapping the "transfer" button, you'll then select where you want the money to go. In this case, we want it in our new You Invest account. Once I've set the amount and transfer date, I'm ready to fund my new account.

Because I've yet to make any trades, it's just showing cash. Once we buy an equity, ETF, or bond, this will change.

I opted to buy one share of the SPDR's SPY exchange-traded fund (ETF) for this example. It's one of the oldest ETF's, and aims to track the entire S&P 500 index, a common benchmark for investors. It also has a very low cost-ratio. Choosing such a broad investment will also help me maintain a semblance of journalistic integrity — no stock calls here, sorry!

On the second screen, there's a full rundown of the order details I selected including the full cost breakdown of the trade.

In the roughly 24 hours since I bought SPY I've made about $1.08, or 0.37% — not too shabby! You Invest also has a more detailed "positions" view, which is still pretty sparse given my one share. It's easy to see how this could work to see an overview of your whole portfolio.

The "Portfolio Builder" option — which appears on the app — loads an error message when clicked and asks me to head to the desktop site or use a tablet in order to check it out. Unfortunately, you need at least $5,000 in cash available to trade in order to use the function.

It's accessed through the same login page as a Chase checking or savings account, and has many more options than the mobile app, including this handy chart of asset allocation and account balances.

By 2019, JPMorgan says there will be personalized portfolios that are custom designed and managed. That's similar to a new offering TDAmeritrade announced earlier this year.
