Hi,
Reading on how WL7 can drive an API into TWS for trades at IBKR.
Do these trades includes buying to open and selling to close of options?
Is the $49.99 a one time fee?
It seems using TWS API requires a $0 balance account at IBKR.
Whereas REST API requires a minimum balance.
Was this the reason for the choice of TWS API?
Thanks

All Extension purchases are one time (i.e. not subscription-based).

Yes. Follow the instructions to enter the contract symbol and properties the first time you refer to a futures or option contract symbol. The way I do it to make sure I'm hitting the right contract is enter the extended data to request a chart, e.g., CSCO210618C47;OPT;USD;SMART

Once you've verified the contract, you can use just the symbol part, e.g., CSCO210618C47, for future chart requests or orders.

Re: REST API
Interesting. I wasn't even aware that it existed until now. Since you can use the current adapter with the IB Gateway too, I don't see any striking advantages yet, but when we run out of things to do...

Try to get historical option date of CSCO210618C47 from IB and get error

"4/23/2021 16:30:10:803" "Interactive Brokers" "Error getting History (CSCO210618C47): Object reference not set to an instance of an object." "Object reference not set to an instance of an object."

I can't duplicate that, but make sure:
1. You're entitled to the data. If you can see it in TWS, you can get it in WL7 too.
2. the first time you enter an option symbol, define the contract like this: CSCO210618C47;OPT;USD;SMART

I already had the 47 defined, but here's what I get by entering CSCO210618C45 first:
CODE:
--------------------------- Wealth-Lab 7 --------------------------- Could not obtain historical data for symbol: CSCO210618C45 --------------------------- OK ---------------------------


But then entering CSCO210618C45;OPT;USD;SMART



And, thereafter you can now just enter CSCO210618C45:



Let us know if you're still having trouble.

Strangely, I'm having trouble getting the Daily bars. Looking into that! Try with intraday scales for now - and remember it takes a LONG time for IB to return 1-minute data via the API, so be patient with those requests. I'd recommend 30-minute bars to get started.

Edit:
Tools > Log Viewer has part of the answer (always a good idea to check that for data errors) -

IBConnection
162: Historical Market Data Service error message:No data of type EODChart is available for the exchange 'BEST' and the security type 'Option' and '5 y' and '1 day'

It turns out that IB doesn't provide Daily bars for Options - try it in TWS - the "Daily" intervals are not available for option charts.

In the next Build of the IB Broker Provider, we'll avoid the Daily bar request for options and quickly return this message to the Log Viewer:
