Issue on Ubuntu Mate.

[Ianfinn1994]

Want to run it on my Raspberry Pi and have the crontab execute every 10 minutes. Getting this issue when building the image.

standard_init_linux.go:211: exec user process caused "exec format error"
failed to resize tty, using default size.

How could this error be rectified? Everything else is cool on the windows version.

[brndnmtthws]

Currently only amd64 is supported, not ARM.

In theory you should be able to get it working on ARM, given it's just a Java app, but I haven't tried.

If you want to try it yourself, you can build the Docker image locally (on your rasppi) and see if it works. Most likely it will fail, because we're currently using the bundled JVM instead of installing OpenJDK 8.

[brndnmtthws]

Digging a little more into it, they do some really weird stuff in the TWS installer. Not only do they try and force a specific version of the JVM, but they also pin it to amd64. I think it can be overridden, but it requires modifying the installer. or bypassing it altogether.

[brndnmtthws]

Honestly, this whole installer is a massive dumpster fire. One option is to extract the files and copy the jars out manually from an amd64 machine.

I hope IBKR hires some engineers who know what they're doing some day.

[brndnmtthws]

Okay, after a lot of futzing about I think I have something that works with 08e20bd. Assuming the Docker build succeeds, you can try the latest now on your rasppi.

[Ianfinn1994]

wow thank you so much man
also yea its like they dont want the little people to make money.

[brndnmtthws]

also yea its like they dont want the little people to make money.

The name of the game is to get the money out of your pocket and into theirs.

[Ianfinn1994]

Also boss, can I try this again on Ubuntu mate? I know the error has to do with the pi's processor. The docker build was successful on raspberry picks until the processor error came up. Is there any way to recompile the code using a compiler for the pi? I can figure it out just like I sort of did with this project. Or should I keep trying with pi os?

[brndnmtthws]

The image is available for arm now, do a docker pull brndnmtthws/thetagang:latest and it'll work.

[Ianfinn1994]

pi@delos:~/thetagang $ docker run --rm -i -v ~/thetagang:/etc/thetagang brndnmtthws/theta

Running on Raspberry Pi OS

[brndnmtthws]

I didn't realize Pi OS was still 32 bit. I had a really tough time getting the armv7 OpenJDK working properly so I dropped it. Let my try something else.

Pi OS does have a aarch64 release, but it says they don't recommend using it for some reason.

[Ianfinn1994]

It may be on the raspberry pi os? Yea i have an older pie that i put together with a GPIO fan and heat syncs. I want to have it run 247 with my IBKR stuff. You are a boss Brendan. Thank you very much. If you cant get it to work, ill try this raspberry image you suggested.

[brndnmtthws]

Here you go:

Should work on both 32/64 bit arm.

[Ianfinn1994]

YAAAY!!! thank you!!!

I compiled everything on my pi and it was working. I keep getting this error call in the sync log.

2021-02-05 18:48:31,034 ib_insync.client ERROR API connection failed: ConnectionRefusedError(111, "Connect call failed ('127.0.0.1', 4002)")
2021-02-05 18:48:31,034 ib_insync.client ERROR Make sure API port on TWS/IBG is open

Ill try updating my systems copy to the image you just published. See if that corrects the error. Thank you so much again boss, this has been such a huge eye opener. Ive learned a decent amount about coding thanks to this project.

[brndnmtthws]

2021-02-05 18:48:31,034 ib_insync.client ERROR API connection failed: ConnectionRefusedError(111, "Connect call failed ('127.0.0.1', 4002)")
2021-02-05 18:48:31,034 ib_insync.client ERROR Make sure API port on TWS/IBG is open

There could be a lot of things causing this. Most likely, for some reason, TWS is not launching properly. I've tested on aarch64, and it does work, but I don't have an armhf machine to test with right now.

[Ianfinn1994]

I used raspberry pi os.
Maybe try with Ubuntu mate?

[Ianfinn1994]

I installed the new docker image and tried to run it. Noticed you added a minimum pnl variable. How do i set it to 50%? 0.5?

[brndnmtthws]

It should be a float. 1.0 is 100%, 0 is 0%, 0.5 is 50%. I meant to make that value optional, that was a mistake.

I might change the behaviour of that too. I'm worried about the case where you sell covered calls, and they end up deep ITM. Currently my preference is to roll them, but that may result in margin getting eaten up if they're grossly mispriced. If the P&L is something like -100%, you'd have to set that value to -1 for them to be rolled.

[Ianfinn1994]

I had tried to put 1.0 in and its still returning errors.

[brndnmtthws]

The newest image hasn't been published yet, you'll have to wait a while for it to finish.

[Ianfinn1994]

How goes the new image, boss?

[brndnmtthws]

The image is available, and it should work on both armv7 and aarch64/armv8.
