Recently Intraday Straddle sellers are on the rise and so the questions to us about how to plot intraday straddle spread dynamically during the day. And Build a Historical chart to visualize weekly options / monthly options spread. In this blog you will learn how to create dynamic Intraday Straddle Charts using Amibroker
A short straddle is an options trading strategy where an investor sells both a call option and a put option with the same ATM strike price and expiration date.
Requirements
1)Realtime Datafeed with Options Trading Instruments loaded in a Watchlists. Also, make sure that the symbols are loaded into the data manager
In my case, I used Globaldatafeeds for Realtime Option Chartst to build dynamic intraday straddles
