0dte Anchored Expected Move by SyntaxGeek

2024년 12월 17일

Here is a script that's making use of TradingView's new option data feed, without the OPRA data feed I'm unsure this script will be useful as the data will be delayed and I've not tested it without the data subscription.

The script is meant to demonstrate use of options data to generate ideas in the community and perhaps be a useful tool for 0dte traders.

For securities that have 0dte I like to calculate what I call the "opening expected move", it's just like expected move (EM) but it's a snapshot of the EM value at open and remains static throughout the day.

Expected move is the value of an "at the money" (ATM) call and put combined and then added t the price of the underlying.

For example if SPY opens at 600 and the ATM call + put premium (debit) is 3 dollars, then the EM high is 603 and the EM low is 597.



These levels are often areas where the market will react as any breaches of these prices could potentially be something that market participants will have to respond to being that something has hit the market unexpectedly.

Additionally, I've added calculations for half EM plots and live premium calculations for the ATM call and put from the open.



It's a fascinating script and it's fun to watch the premiums during periods of market volatility or a chop range day.

I make no guarantees for any of the data presented and there could be bugs as options data is still quite new in TradingView and I've not spent a long time coding this or testing.

Enjoy!

1. Fixed a bug with contract string parts leading in 0 (embarrasses I missed this one :D)
   
2. Added logging for the contracts being selected on day change so you can debug data if you see issues.
   

Important note
If you're seeing errors, you'll want to open settings and adjust the date to be no less than a week or so back, this is due to TradingViews max historical symbol lookup per script and was the only workaround I've found so far. Once you set it, you should be good for a couple weeks.

You can of course adjust each day but it can be tedious.
