To all Option Wheel strategy traders: This app makes it super easy to calculate your annualized yield in just a few seconds - which is the key to properly execute income strategies in option trading. Especially when trading mobile, this App will enable you to improve and speed up your decision making significantly - by providing you with annualized yield figures in a snap. You can set relevant parameters and see how adjusting these parameters will impact your yield. You no longer need to rely on your gut feeling, since you will get reliable yield indications super fast: * Pick your strike price and optionally margin requirement * Slide your option premium up and down * Play with different expiration dates * Simulate yield impact of closing an option position early * Set your individual brokerage fees and tax rate -> You will see your calculated annualized gross yield, yield after fees and yield after fees & taxes (cash secured and on margin) About the Option Wheel strategy: In this strategy, the option trader aims at increasing his yield and collecting additional cash flow by repeatedly selling Cash Secured Put Options until assigned. Then, in the shareholder phase, the investor is collecting dividends and keeps selling Covered Call Options until assigned again - which brings the investor back to the Cash Secured Put phase. The strategy can be optimised, when the investor avoids assignment by rolling the position. The investor would aim at yields that are above the long term market average - to compensate the additional work he needs to invest. This calculator was developed to support on this endeavor. **DISCLAIMER** The information shown in the app does not represent any investment or investment strategy recommendations for trading in securities, but serves solely for personal information or entertainment and is in no way to be understood as an invitation to trade in securities.

Sentiscale reads the market's mood and puts it in one number. Free: the gauge, every widget and your own alerts. No ads, no account. Every day it scores the market's news flow, blends it with how stocks, volatility, credit and safe havens are actually behaving, and gives you a single 0-100 reading from extreme fear to extreme greed. For the US, Europe and Asia, with the crypto fear and greed index alongside. WHY THE GAUGE MOVED Most fear and greed gauges show you a number and stop there. Sentiscale explains it in two plain sentences, tied to the specific headlines behind the reading, so you can tap through and check the reasoning yourself. WIDGETS AND ALERTS Put the gauge on your lock screen, or stocks and crypto side by side on your home screen. Set your own alert lines, for example "tell me when the US gauge drops below 25", and get one notification when it crosses. Optional pushes also tell you when the mood shifts sharply or a high-impact headline lands. WHAT USUALLY HAPPENED NEXT When the gauge has sat in this band before, how did the market behave over the following month and quarter? Sentiscale shows the historical pattern next to the baseline, and flags a band as thin when the sample behind it is too small to lean on. SECTOR BY SECTOR Eleven sectors, each with its own mood reading, so you can see whether the market is uniformly nervous or just nervous about one corner of it. AN OPEN TRACK RECORD Every daily call Sentiscale has made is published, alongside what the market actually did afterwards, misses included, next to the benchmark you should judge it against. Nothing is edited or removed. SENTISCALE PRO The gauge, the widgets, alerts and the news feed are free, always. Pro unlocks the daily explanation, the historical band patterns and the per-sector breakdown. Subscriptions renew automatically unless cancelled at least 24 hours before the period ends; manage them in your Apple Account settings. Terms of Use (EULA): https://sentiscale.app/terms.html Privacy Policy: https://sentiscale.app/privacy.html Sentiscale measures sentiment. It is not investment advice, and it does not predict prices or tell you what to buy or sell. Always do your own research.
