The new Option Chain feature in Tradier extension B24 is FANTASTIC!!!!!
I whipped up sample code (included at end of post) that shows the power of this new capability for trading options with WL. This demo selects a Call option for an underlying with a monthly expiration at least 31 days out. It requires that the Greek Delta be between .4 and .6 (close to the money) and that the price of the option does not exceed its allocation. It then selects from candidate options that meet these criteria the one that maximizes transaction value. These are just some examples of the types of complex rules you can apply to option selection, using the power of Linc statements in C#.
The sample code replaces 336 lines of code in my working strategy and eliminates 90+ % of calls made to the broker for option data!
I did come across a couple of glitches, which could be related to each other:
1. There is some strange caching going on either in WL or at Tradier that keeps populating an option chain fetch with results from previous fetches on other symbols.
2. Option chain requests return stale chain data from Tradier as time goes on, after the initial fetch that followed a WL restart.
Caching
A snap of the debug log on a three-symbol dataset shows how, after clearing the Option List, the next symbol fetch returns data from previous symbol fetches and includes it with the new.
Stale Chain Data
Here's a thread I had with Tradier tech support:

I just pulled the chain to confirm these details and here is what I got from our data provider:
https://documentation.tradier.com/brokerage-api/markets/get-options-chains
{'symbol': 'PLUG240719C00003000', 'description': 'PLUG Jul 19 2024 $3.00 Call', 'exch': 'Z', 'type': 'option', 'last': 0.53, 'change': -0.13, 'volume': 38, 'open': 0.59, 'high': 0.59, 'low': 0.52, 'close': None, 'bid': 0.5, 'ask': 0.54, 'underlying': 'PLUG', 'strike': 3.0, 'greeks': {'delta': 0.6479942833699219, 'gamma': 0.3366493682351791, 'theta': -0.0035140679977920266, 'vega': 0.004686660601744747, 'rho': 0.0021265099103928813, 'phi': -0.0027956345185813397, 'bid_iv': 0.830937, 'mid_iv': 0.841645, 'ask_iv': 0.852352, 'smv_vol': 0.857, 'updated_at': '2024-05-23 16:59:06'}, 'change_percentage': -19.7, 'average_volume': 0, 'last_volume': 3, 'trade_date': 1716483729345, 'prevclose': 0.66, 'week_52_high': 0.0, 'week_52_low': 0.0, 'bidsize': 4141, 'bidexch': 'D', 'bid_date': 1716484690000, 'asksize': 152, 'askexch': 'D', 'ask_date': 1716484688000, 'open_interest': 416, 'contract_size': 100, 'expiration_date': '2024-07-19', 'expiration_type': 'standard', 'option_type': 'call', 'root_symbol': 'PLUG'}
It shows the update as being in the last hour (time is in UTC so 16:59 is about 13:00 EDT). Sometimes when volume is very very low on particular options they can go without an update for a bit but in this case, it looks like it has been updated.
All the best,

Hello.
Using the API to get an option chain for symbol plug at 12:50 Eastern time today 5/23 returns the following:
PLUG240719C00003000 0.71 0.55 0.59 0.57 5/22/2024 7:59:50 PM
This is a $3.00 strike call option with a delta of 71. The other numbers are (in order) bid, ask, midpoint, and last updated. Note last updated is from 7:59 PM yesterday (not sure what time zone that is). I understand that option chains for the API are only updated once an hour at Tradier, but why not since yesterday? The information is so out-of-date as to be useless.
Is there a way to get real-time bid, ask, midpoint, or last price?

A 1-liner fix. Too bad I missed that detail the first time through, but thanks for reporting it.

@Cone Nice! Do you think this had anything to do with not fetching the latest chain data? Is that fixed as well?
What other broker extensions does the Options Chain fetch work for?
(after modifying lines 8 and 58 of the excellent example code accordingly)
I tried using (without any yield):
8 using WealthLab.IQFeed;
58 optChain = IQFeedHistorical.Instance.GetOptionChainSnapshot(uSym, expDate, OptionType.Call, lStrike, hStrike, 10);
[unfortunately, I can't get a Tradier account]. Does it work for the Medved extension (with Schwab or Fidelity as data source)?

Re: innertrader
I'm not sure about the latest data. As long as successive requests are 3 seconds apart, we'll request a refresh. I'll make sure the refresh is working next week.
I'll convert the UpdatedAt time from UTC to EST since we're generally supporting only U.S. options.
Re: bcdxxx
You can get the full OptionChain from IQFeed but they don't return greeks. For their apps, they calculate the greeks to display them. GetOptionChainSnapshot (used for a single expiration) is currently only available for Tradier, for IB with the next build (51), and probably Schwab when that happens. (We just added the function to the API, so Medved would have to implement it.)

QUOTE:Found the bug here too. We'll get these corrrections out later this week in Trader build 26.

fyi, (Tradier greeks)
Although this is fixed (in dev) from our side, it looks like the greeks don't really update until at least 10 minutes after the hour.
This request was performed about 12 minutes after the hour and still several symbols still returned greek data from the previous hour. It wasn't until about 18 minutes into the next hour that all symbols returned the "latest" data.
For the latest data, you'll be able to use IB the same way, but the same request take several seconds longer for every symbol. The IBHistorical method has to use subscribe to every symbol in the chain (within the strike contraints) and wait for a streaming update to get the greeks. There are tradeoffs for either provider.
