Common questions
Is ORATS a good alternative to Market Chameleon?
Yes, for traders who screen by volatility and earnings; both cost $99 a month. ORATS Trading Tools includes real-time data, a backtester for your own rules on data since 2007, and order routing to Interactive Brokers, TradeStation, and Tradier. API access is a separate ORATS product, from $199 a month.
Does Market Chameleon have a backtester?
It has preset backtest reports: 30+ earnings strategies over the last 12 quarters, week-long ATM straddles with a 1 to 26 week lookback, and per-symbol strategy benchmarks. Entries and exits are fixed or chosen from menus, and you cannot set your own deltas or days to expiration. ORATS backtests your own deltas, days to expiration, entries, and exits on daily data since 2007, and on one-minute data since October 2020 for about 140 symbols.
Is Market Chameleon real-time?
No. Its pages state that market data is delayed 15 minutes, and its terms of use say stock quotes may be delayed at least 20 minutes. ORATS Trading Tools includes real-time data once you sign the OPRA and Cboe agreements in the dashboard; delayed data works without them.
Does Market Chameleon have an API?
No public one. Its developer page says a Web/REST API is not available, and its terms prohibit automated retrieval. It sells data feeds from $500 a month each and quotes custom feeds on request, with Web API delivery. ORATS sells a Data API from $199 a month, Tools APIs for scanning and backtesting as add-ons from $99 a month, and includes a CLI for AI agents with every API plan.
