Queue gets filled by the listener thread and the data can be pulled in the while loop. Let me know if any confusion. Be sure to disconnect before clearing the variables, as the listener thread will still be running.

Just figured how to use IB API from spyder. With threads and queues. Let me know if anyone interested to know.

True. But tws API seems robust and the features it supports seems difficult with other technologies. Please correct if I am wrong

Can you please explain what do you mean by this? Are you speaking about tws API or something else?

I think Matlab has prebuilt library for IB. If you have access to matlab then it’s better than python hands down. Most people use python because it’s free.

What’s the idea of cancelling and placing such small increment orders within a minute? Is your algo benefiting from that small change in the fill price within that minute? Just curious

Not sure, but seems main logic would be the maintenance of the “book” for each instrument. That is the bid and the offers. Now we then match bid offers that match

You want to create your own exchange?

True. There is a digital feudalism coming. Big software is consolidating power. Truly scary times ahead for the digital world.

Doesn’t this mean that you can sell and buy from yourself and in the process pay brokerage? How will that help?

Just download anaconda, install and launch spyder. You will have everything you need pre packaged. Will also come in handy when you want to finally automate.

No need to jump ship just because this might be the future. We can jump when it becomes main stream. Also they are easy to switch to.

I have written an historical data downloader for myself in python for IB. It is designed with pacing violations in mind and uses IB API. (keystrokes are for 1980s) It has an UI also. (I don’t like to read my own code:D:D:D).

For future reference, if someone thinks python can’t do something simple, they are probably wrong. Try googling “python anti gravity”. That’s how powerful python is.

I might be wrong but this is what I am thinking. You monitor the bid/ ask price. When ask/bid price is at the level that you want you fire a market order. Let me know if i am missing something.

Yes, I also would like to know this.

I don’t understand this poll. Isn’t the whole interface easily editable. You just unlock the pad lock, move windows as you please, close windows you don’t want, add additional windows you want. Then re lock it again so that the windows are fixed. You can create as many screens as you want like...

Sorry, to be perfectly correct in my previous comment, whether we are able to place multiple orders at once or check fill of multiple orders at once is not dependent upon REST technology but dependent upon the brokers API.

I finished step 1. But for step 2 i am working on my own system. I hate using something which i do not understand. Not sure whether this will change future steps.
