It's very easy: you create a subaccount that has its own number and login and funding. you fund it with your casino money and connect it to an algorithm. I trade 5 algo's like this and I can see all activities of the algo's in my main account

Thanks, Peter! I check the sub-account creation. Might be a good idea to insulate different pools of money anyway even though it has not been an issue with manual trading.

I would appreciate if you shared your findings here.

Furthermore for Qs here - is it possible to create several such sub-accounts and have them connected to different Quantopian algos?

Does the $1M per account limit apply to entire account or each subaccount?

From the Quantopian system perspective, we need a unique username/password for each algorithm you trade. The Quantopian system won't know (or care) if it is connecting to a sub-account or not. To repeat something that I'm sure you already know, you cannot connect two algorithms to the same account. But if you instead add a sub-account, then that works just fine.

The $1 million limit is applied to your Quantopian account. If we've removed the $1 million limit for you, the limit is removed for all of your IB accounts.

@Dan

Can you explain how this limit works in practice.

If I have $1.5M in an account and connect an algo to it what exactly happens?

The same question if I have two $750K sub-accounts each connected to different algo?

If you deploy an algorithm to an account with $1 million, it will stop trading and you will get an email.

If you want the limit lifted, hit the "contact support" link in the nav. That will start the process of lifting the limit.

Good to hear about the 'lift limit' feature.

Just from a knowledge base standpoint if you connected two alogs to two $750K IB sub-accounts that would work fine?

Here are the sub-account creation instructions for Interactive Brokers. https://www.interactivebrokers.com/en/software/ptgstl/topics/ptgsubaccounts.htm

I will set up something with the small amount of money this week and report this thread if there are any hickups.

Btw. Found one really annoying limitation with IB sub account. They need separate data subscriptions from IB standpoint. Sure you can trade using Quantopian data but I had some rather expensive learning in the past around IB accounts without data subscriptions.

What I learned is that if you need to manually stop your algo from TWS console. ''close all positions (panic button)" does not work without a data subscription. You need to make manual sales order for each position you hold.

I am also going to check how sub-accounts affect on account margin but now sure yet. I am not trading Quantopian one with leverage, but I have some leveraged positions elsewhere.
