OptionsKing vs Market Chameleon
Market Chameleon gives you a great deal of options data and leaves the judgment to you. OptionsKing gives you far less data and makes one judgment for you: how good a strike is on a 0 to 100 scale, and where that puts it in the order. If you like doing the analysis yourself, Market Chameleon is the stronger tool.
Market Chameleon is a research terminal. OptionsKing is a filter with an opinion. People end up comparing them because both surfaces show covered calls and both show implied volatility, but the reader they are built for is not the same reader.
| OptionsKing | Market Chameleon | |
|---|---|---|
| Coverage | 60 tickers on the public pages, your watchlist in the app. | Broad US equity and options coverage. |
| Earnings analytics | Earnings date as a veto inside the expiry window, nothing more. | Deep historical earnings-move and implied-versus-realized studies. |
| Screens | Six fixed screens, all premium-selling. | Many, highly configurable. |
| Withholds weak results | No. It scores them and lists them highest first; you judge. | No. It shows you the data and you judge. |
| Tracks what you earned | Yes, per trade, against buy-and-hold. | Not the focus of the product. |
| Price | Free. | Paid subscription with a limited free account. |

We are not quoting a price for Market Chameleon because their site would not serve an automated read on August 4, 2026 and a subscription price is not a fact worth repeating second-hand. They also sell several differently named plans, which makes any single figure misleading. Get the current number from them.
What Market Chameleon does better
Earnings analytics. The historical earnings-move data, the implied-versus-realized studies and the volatility screens go deeper than anything OptionsKing has or plans to build. If you want to know how NVDA has actually moved on the day after its last twelve earnings reports, against what the straddle was pricing going in, that is their page and there is no version of this site that competes with it.
Configurability too. Their screeners bend to what you want to ask. OptionsKing ships six fixed screens and no filter builder, which is a limitation and is meant to be one.
What OptionsKing does differently
It scores. The number runs 0 to 100, it is deterministic, and every card carries it next to the trade it describes. What a terminal gives you is rows and a filter language; what this gives you is one opinion per candidate, computed the same way every time. Neither of them decides for you.
The distinction is worth being precise about. More data is genuinely better if you have the time and the discipline to work through it. Most people selling four covered calls a month have neither, and the failure mode is not a lack of information, it is talking yourself into the juicy strike on the thin chain. A bar you cannot argue with is aimed at that specific failure.
The other half is the ledger. The app records what you actually collected on the trades you told it you took, including the ones that went badly, and reports the real number against what you would have made just holding the shares. Most tools in this category stop at the idea. Whether the idea worked is the only question that pays you.
Where OptionsKing is weak
It is new. Both apps are in the stores, both listings are new, and the review counts say so. It covers 60 tickers on the public data pages, not five thousand. It does one strategy family, premium selling, and it has nothing to say about spreads, calendars, or anything you would put on in a directional bet.
And the bar cuts both ways. On the first public snapshot, taken in a dead-flat low-volatility tape, not one strike across all 60 names cleared it. Zero. A screener with a looser bar would have handed you a full page of ideas that week, and some of them would have worked out fine.
Market Chameleon has been at this for years across the whole market. On raw analytical surface area it is not a fair fight and pretending otherwise would be silly.

Questions people actually ask
Is Market Chameleon free?
There is a free account with limited access, and the deeper analytics sit behind a paid subscription. They sell several separately named plans, so check their site for the current structure and price.
Does OptionsKing have earnings data?
It knows when the next earnings date falls inside the expiry window, and that event risk feeds the score. It does not publish historical earnings-move studies. Market Chameleon does, and does it well.
Which one finds higher premiums?
Market Chameleon, almost certainly, because it screens a far wider universe and does not withhold results. OptionsKing will show you fewer trades on purpose, and on a quiet week it will show you none. High premium and good trade are not the same screen.
