I use this app a lot!

I usually don't give app reviews, but I love this app so much, I'm making an exception! I use this app more than the TOS software on my computer. The app enables me to check my positions and make trades anywhere. I check it several times a day...more than I check Facebook. It has become my "go to" for checking the market, looking at my positions, and making trades. I make options trades while waiting in my car, and even while grocery shopping, etc. It is immediate, relevant, and allows me to keep track of my positions on the go. There are a few glitches that I've found (like OTM% on options changing to all zeros every once in a while), but the glitches are so minor compared to how glad I am that this app exists. It works very well as a whole, and I recommend it to anyone.

same as TD Mobile Trader

I was told thinkorswim would be a better interface than the TD Mobile Trader app, but they are essentially the same. The “positions” tab doesn’t clearly tell you your basis in a position, or its current market price, and doesn’t have a quick trade button to allow you to close that position right there. (At least this is the case for options.) I end up going to the underlying stock quote and looking at its options chain to see the bid/ask for my contract (and I trade it from there if I want to close).
The “positions” tab does tell you p/L for the day, based on the last trade, but not based on the current bid/ask which is what I really want to know.
Also for stock quotes, there isn’t a good “fundamentals” snapshot where you can see some basic metrics about the stock like P/E, mcap, FP/E, P/B, short interest, profile, etc like Yahoo Finance or Google Finance would give you. I end up looking up the stock elsewhere then coming back to the app to trade— it’s not remotely capable of research.
App is secure and functional, however, and I haven’t had any problems with my trading.

The Ignorant Pro

I am an exceptionally, uneducated, 70 something that spent my adult life driving trucks across this great land of ours. After I retired, I decided to try my hand at a little day-trading. Did I say ignorant? Maybe ‘dumb’ better describes me. Anyway, after that colossal disaster, I downloaded THINKORSWIM ...that’s when things got worse. I couldn’t figure out what I was looking at or how to do anything. But, guess what, THINKORSWIM has many, many ways of learning the platform. And, I learned.
Here’s my point; if I can learn this absolutely, terrifically designed, user friendly platform, and be profitable can you. By the way, the support level is more than you’ll ever need to master it. Whether you trade stocks, options, futures, Forex, etc, this platform will do it all ...and quite well, may the add.
