WEBVTT 00:00.120 --> 00:05.360 So the other thing to show you the bigger change is a new class called Trading Floor. 00:05.360 --> 00:06.720 And it's really simple. 00:06.760 --> 00:08.200 It's this is all it is. 00:08.400 --> 00:13.760 And this represents our our set of traders, our three traders. 00:13.880 --> 00:14.600 We're not using that. 00:14.640 --> 00:15.320 So we'll take that out. 00:15.320 --> 00:17.400 We're not not using agents at all here. 00:17.720 --> 00:19.720 Um, so here's how it works. 00:19.960 --> 00:24.840 Uh, it has a, a function here called traders that, that returns a list of traders. 00:24.840 --> 00:26.720 And they are Alice, Bob and Carol. 00:27.120 --> 00:32.880 Alice and Carol are using deep seek, and Bob is just using Gpt4 and mini, which is the default. 00:33.120 --> 00:34.280 And so this just returns. 00:34.320 --> 00:36.000 Alice, Bob and Carol ABC. 00:36.680 --> 00:43.880 Uh, and then this, this is the, uh, this is the main this is the business, uh, async def run every 00:43.880 --> 00:44.920 30 minutes. 00:45.200 --> 00:47.880 Uh, and it's just an infinite loop. 00:47.880 --> 00:50.280 And it says while for while true. 00:50.280 --> 00:53.040 So it goes on forever for trader in traders. 00:53.400 --> 01:00.120 Uh, and then it just runs the trader, which you remember flips between trading and rebalancing. 01:00.120 --> 01:03.360 And then it goes to sleep for half an hour and then it will repeat. 01:03.520 --> 01:05.640 And I need to add an exception handler in here. 01:05.740 --> 01:10.100 Otherwise, any time that any of the anything goes awry with our agents, it will just stop. 01:10.100 --> 01:11.460 So I'm sure I will do that. 01:11.460 --> 01:12.460 I'll have some more. 01:12.620 --> 01:15.980 Some more, uh, belt and braces by the time that you see this. 01:15.980 --> 01:17.820 Or you can add on some more stuff to. 01:17.980 --> 01:20.740 And it would be good to have some various guardrails in here. 01:20.940 --> 01:22.540 Um, but that's fine for now. 01:22.540 --> 01:28.660 And having a time.sleep in your code is generally frowned upon in normal Python, because that would 01:28.660 --> 01:30.300 be holding things up. 01:30.300 --> 01:35.420 But when you're using Asyncio, this is this is considered a perfectly decent, uh, and it means, 01:35.420 --> 01:39.980 of course, that it's not not going to be working at this point, but it will be, uh, giving up for 01:39.980 --> 01:44.860 any other for the event loop to run anything else that was awaiting at the time. 01:45.540 --> 01:48.740 Uh, and so this is just something that runs. 01:49.020 --> 01:56.180 And this brings me to saying that the way that you run this is you simply bring up a terminal and then 01:56.180 --> 02:00.380 you do you've run trading Pi to set the trading floor going. 02:00.620 --> 02:01.660 And that's what we'll do. 02:01.660 --> 02:05.260 So you remember that it's control and backtick to bring up a terminal. 02:05.300 --> 02:06.180 Here it comes. 02:06.660 --> 02:09.900 And now we go into the sixth folder and now we type. 02:09.940 --> 02:22.250 You've run trading floor.py and off it goes and it will start doing stuff and you'll see it doing things 02:22.250 --> 02:30.250 as it goes, as it's reading stuff in and doing things and starting to work at making trading decisions. 02:30.690 --> 02:37.610 And so we will this leave this running as it does its thing, while I bring you over to the last thing 02:37.650 --> 02:38.570 to show you. 02:38.570 --> 02:42.450 And of course, the last thing is a gradio user interface. 02:42.850 --> 02:46.370 And now look that, you know, the the purpose of this course is not user interfaces. 02:46.370 --> 02:50.970 So I'm not going to go through this in much detail other than to point out a few things that are quite 02:51.010 --> 02:52.170 satisfactory. 02:53.010 --> 02:59.370 I've got in here a model class called Trader View, which is just used to be like a user interface sort 02:59.370 --> 03:07.210 of control class that sits between the UI and the business logic, and it holds a trader underneath 03:07.210 --> 03:11.410 it, so it holds one of either Alice or Bob or Carol. 03:11.410 --> 03:15.990 And we're going to have three parts of the user interface, one for each of our traders, and there 03:15.990 --> 03:19.310 will be a trader view created for each of those three. 03:19.710 --> 03:25.870 And the trader view is going to be responsible for returning each of the bits of information that will 03:25.870 --> 03:29.070 populate different parts of the user interface, as you will see. 03:29.430 --> 03:32.910 And there is, for example, a chart to show the value of the portfolio. 03:33.190 --> 03:36.670 There's some stuff to organize that chart. 03:36.710 --> 03:42.430 There's something that shows the current holdings in the portfolio and various other bits and pieces. 03:42.830 --> 03:48.150 The balance, the PNL and then then all of these components get, get returned. 03:48.510 --> 03:51.710 And then there is agent UI component. 03:51.710 --> 03:55.590 This is the user interface that goes alongside this trader view. 03:55.630 --> 03:59.110 This is a user interface that represents one of our three traders. 03:59.110 --> 04:05.910 And again you know, the knowing how to make nice gradio UIs comes comes with some practice and is not 04:05.910 --> 04:07.070 particularly part of this course. 04:07.070 --> 04:09.190 But do take a look at it if you're interested. 04:09.550 --> 04:14.830 Um, and then the thing that, that it all comes down to are these callback functions. 04:14.830 --> 04:22.220 That's what what, uh, gradio is so powerful at, uh, and the callback functions is where the user 04:22.220 --> 04:25.340 interface is able to call in to get various things to happen. 04:25.940 --> 04:32.380 And then yeah, this this just shows that if there's a run button, if it's clicked, it will call run 04:32.420 --> 04:33.340 all agents. 04:33.460 --> 04:35.940 The inputs are all of the states of the agents. 04:35.940 --> 04:39.300 The outputs are all of the components that they need to be displayed in. 04:39.300 --> 04:44.020 So Gradio automatically hooks up the inputs with the outputs of this function. 04:44.020 --> 04:45.180 Run all agents. 04:45.620 --> 04:50.100 The refresh button refreshes the UI it calls UI refresh. 04:50.260 --> 04:52.940 Again, all of the inputs are hooked up to the states. 04:52.980 --> 04:55.220 All of the outputs are hooked up to the components. 04:55.500 --> 04:58.420 When you load the user interface, it will start doing this. 04:58.460 --> 05:04.180 It will start painting the UI, and then it also has a timer that runs to refresh the user interface 05:04.180 --> 05:09.980 every half an hour, so that any time that there's been trading activity, you should shortly afterwards 05:10.020 --> 05:11.860 see that appearing on the user interface. 05:12.060 --> 05:13.260 And that's all there is to it. 05:13.260 --> 05:14.100 That's the UI. 05:14.220 --> 05:15.820 I think it's time that we see it. 05:15.820 --> 05:17.100 So look to set your expectations. 05:17.100 --> 05:21.940 This is still an early version of our autonomous trading platform, and I intend to keep working on 05:21.940 --> 05:22.100 it. 05:22.100 --> 05:26.400 And so you should bring it up as it is right now, because I bet by the time you get here and you're 05:26.400 --> 05:29.240 trying this, I will have made the UI even better. 05:29.240 --> 05:30.720 And it's going to be worth checking out. 05:30.720 --> 05:34.120 But this is the version I have as of now for your your critique. 05:34.480 --> 05:37.760 Uh, we go into the sixth folder and we type. 05:40.200 --> 05:41.080 App dot. 05:42.400 --> 05:44.520 Uh, and that should be it. 05:45.000 --> 05:48.240 And with that it's going to initialize our Gradio app. 05:48.240 --> 05:49.800 And up it comes. 05:49.840 --> 05:52.040 And the first thing it has to do is Alice. 05:52.040 --> 05:58.120 Bob and Carol need to connect the MCP servers and read their accounts and set themselves up. 05:58.160 --> 05:59.920 And while they are doing that, I will flip over. 05:59.960 --> 06:06.000 It takes about 30s, but I did it already a minute ago and here is what appears when it's done. 06:06.360 --> 06:12.760 And you can see the three traders appearing Alice, Bob and Carol in our trading floor simulator. 06:12.800 --> 06:14.720 You can see the activity down there. 06:15.040 --> 06:18.440 Uh, you can see their strategies, which will evolve over time. 06:18.440 --> 06:23.280 You can see the rather sorry state of affairs that even though this is just from very recently, already 06:23.280 --> 06:25.640 all three traders are in the red right now. 06:25.760 --> 06:28.240 But it has been a terrible day in markets. 06:28.480 --> 06:32.180 Uh, and there's some sort of a graph that's showing the change in position. 06:32.180 --> 06:36.580 It's just this is only since I kicked it off, I reset just just like an hour ago. 06:36.580 --> 06:39.660 So we're not we're not seeing much activity yet. 06:39.900 --> 06:41.540 These are small changes. 06:41.740 --> 06:46.820 And if I scroll down we see against each trader their holdings in terms of the stock symbol and how 06:46.820 --> 06:48.740 much they have in their portfolio. 06:48.860 --> 06:54.100 And then below that, you've got all of the transactions listed down there, along with the rationale 06:54.100 --> 06:56.540 of why they made the transaction that they did. 06:56.740 --> 07:03.020 And then at the bottom are buttons to refresh everything as of right now, or to ask the traders to 07:03.060 --> 07:03.540 trade. 07:03.540 --> 07:07.380 Right now they are trading every half an hour, of course, in the trading floor. 07:07.420 --> 07:12.860 But you can also kick off a trade right now by pressing that button and it will go off and do its thing, 07:12.980 --> 07:14.380 um, as we had done in the lab. 07:14.380 --> 07:20.020 And of course, if we flip over here, uh, this has, has uh, has already refreshed and these axes 07:20.020 --> 07:21.540 start at 0 to 1000. 07:21.540 --> 07:28.180 But actually if you resize it, it shows it to be just, just the, uh, the sort of $5 differences. 07:28.580 --> 07:31.860 Um, so that is the user interface. 07:31.860 --> 07:34.580 And it's a lot of fun if you ask me. 07:34.580 --> 07:37.570 And this is something that you can just leave running. 07:37.570 --> 07:42.450 And while I was building this, I'd leave it running for long periods of time and in different market 07:42.450 --> 07:42.970 conditions. 07:42.970 --> 07:44.690 You will see things changing. 07:44.810 --> 07:50.250 And of course, I should turn my phone off silent, because there will indeed be pings coming through 07:50.730 --> 07:51.650 as trades happen. 07:51.690 --> 07:57.770 I can I can show you some of the notifications that I've had, um, or I've had I've had a lot of notifications 07:57.770 --> 08:03.290 because this has been running uh, there they all are executed trades executed, trades executed trades 08:03.290 --> 08:08.930 with, with uh, the summaries and with the current portfolio and with all of them reporting their slight 08:08.930 --> 08:09.610 loss. 08:09.850 --> 08:12.250 Uh, it's very entertaining. 08:12.250 --> 08:13.450 It's very exciting. 08:13.490 --> 08:18.650 It's it's truly autonomous that these are making their own decisions. 08:18.650 --> 08:24.170 And I can't wait to leave these over a long period of time and see what happens. 08:24.210 --> 08:28.610 I mean, first and foremost, whether they actually make money or not, uh, but also to whether their 08:28.610 --> 08:36.010 strategy evolves, whether the memory starts to build from the researcher and exactly how the situation 08:36.010 --> 08:37.050 transpires. 08:37.050 --> 08:38.770 Because I just don't know. 08:38.810 --> 08:40.490 And that is the joy of it.
