1. 5/5Great trading app

   UPDATE: The workaround mentioned in the Developer’s Response works great, so no complaints from me. Although the tab bar navigation has also changed, it can still be configured to replicate the old layout. My only suggestion would be to add a tooltip for the Buy/Sell buttons, which would be displayed the first time that a user views this screen since updating - I think this new functionality is great, but it was not clear to me that those were buttons so it is somewhat unintuitive. Regardless, thanks for the help! Original review: This new update, however, is terrible. It’s not as intuitive overall. So far, the biggest friction that I feel as a user (on both iPad and iPhone) is the inability to create an order directly from a symbol’s screen. I have no idea why that was removed as a feature, but you’ve just made one of the primary user actions incredibly more cumbersome - I now have to tap on Orders, the new order button, type the symbol name, and tap the appropriate row. The worst part is that by the time I’ve performed these additional 5+ taps, I have lost the context of what the trade was that I wanted to perform in the first place. Don’t fix what’s not broken - please restore the former (read as: better, in terms of intuitiveness and navigational ease) user interface. I'm usually not opposed to updated app experiences, but this one is notably worse, and aside from reorganizing the functionality, the only new feature I’ve even noticed is the different view/display options for Watchlists.

2. 5/5Issues

   Love the platform and what it offers but am extremely frustrated with all the technical problems. There’s been countless instances where I’ve placed buy or sell orders that do not go thru. When you check it the color is lighter, it does not allow you to cancel it or make any changes, the order is not acknowledged resulting in enormous losses as you end up having to resubmit orders for a higher price or take a loss on the sales price. When the frozen order doesn’t allow you to cancel or change it, you have to submit a new order for a different price, suddenly the old order (which can sometimes take minutes at a time) suddenly activates and you end up with duplicate orders resulting at even further losses. Another costly problem is when you set trailing stops or stop limits and the stock breezes through it without selling. There’s been numerous other issues but those are the most predominant and costly issues. Of course It’s never Ameritrade the takes the loss, it is the user. If there weren’t so many technical problems I would really enjoy the program and frankly I’m shocked that there hasn’t been lawsuits from all the customers that have incurred monumental losses because of these problems.

3. 3/5Webull > thinkorswim

   When doing a price levels on Webull, they have a feature where the line will automatically straighten for you infinitely from left to right with just one easy, single tap or click. It’s super convenient, when trying to identify support & resistance from previous days, months, even years. Especially on the go where everything is only accessible through the palm of your hands within a small screen. It’s super annoying getting crossed-eyed on trying to see if the price level line is straightened, & it gets even trickier when you want the line longer than what the screen— cellphone or laptop shows, because sometimes when being forced to extend the line manually, you’ll also have to make sure it keeps straight. Also, I hate how when drawing head & shoulder trends, for example, that you literally have to go in & manually add in lines for both heads & shoulders. Can’t there be a feature where you’re able to draw one line, then tap on your the next for the lines to automatically connect, instead of having to create new lines, manuscripts then to make sure the points touch, etc? I have yet transferred my account, because Webulls features when it comes to analytical notation tools are much more convenient, than thinkorswim. Also, is there not a way up preserve my settings when it comes to removing, example, RSI or MACD temporarily? I feel like I always have to keep these in my screen when I don’t always want to see them, but having to change them to my colors of my lines to my preference for easy differentiation is so annoying.

4. 4/5Needs “turbo trader” share size buttons w/ “Buy Bid” “Sell ask” buttons

   The app is usable to trade and pretty decent especially with charting and indicators. Or bc of the free level 2 and the PFOF model that allows for commission free trading. But they could take a page out WeBull’s book in how they designed their mobile app and mobile trading software with “Turbo Trader”. If you’re an active trader that needs to get in and out of the market quickly, it’s essential to have share size buttons and “Buy Bid”, “Sell ask”, “Buy Market”, “Sell Market”, “Flatten” & “Reverse” buttons. The desktop application has those features as well as the web trader. But unfortunately not the mobile app. It’s still pretty good compared to everybody else’s mobile trading software though. Another problem is that there are some bugs like sometimes on the 1 day, 1 minute I’ve seen the chart not be able to scroll to the right but it’s easily fixed by just reloading the chart in a different time period like “5 days, 1 minute” as opposed to the default “1 day, 1 minute”. And there’s also this pretty terrifying glitch where I’ll be trying to put in an order but for some reason it will keep saying “this order cannot be edited bc blah blah” and I have to close the app and reopen it in order to successfully close my position which can be terrifying sometimes. Especially if you need to get out immediately and things are moving fast. That can be really dangerous. Every one of these apps has some bugs though afai can tell. So in summary, pretty good in most ways, especially compared to most others but some serious drawbacks and a bit buggy. Pretty good for charting and technical analysis

5. 2/5App frequently closes on me during trades

   The app over all is great. It has a lot too offer. But there is one issue that happens frequently enough the that it has caused me to one star. The app repeatedly logs me out staying “the session has ended, please log in to continue” the log in screen comes up and I have to type in my password etc and get logged in. This has cost me money in more than one occasion and it always seems to happen right as I’m about to exit a position that is going against me. I be been luck that the moves weren’t more violent and didn’t go further against me while I was getting logged back in. Very irritating. I’ve also had times where I sent and order and it just did t go anywhere. It was like the order never existed after I hit the send button. So I missed a lot of good entries and exits due to this. But besides those too issues I do really like the app. I do wish the would add a few quick execution button on the same screen as the chart…. So you do t have to toggle over to the order tab and hit “send” are you sure “yes”. That’s a 3 step process and a lot can happen in those 3 steps that can cost u money. I suggest 3 execution buttons buttons be added somewhere on the chart tab that can be customized to what type of orders the execute. Similar to the way you can assign hot keys on the active trader tab of the desktop version.
