Frequently asked
Common questions.
How does RMBS implied volatility and the Greeks feed TECHi’s Forward model?
IV surface, delta, gamma, theta, vega, and rho are inputs to TECHi’s documented Forward framework when a provider supplies them. They support short-horizon volatility research and lower model confidence when missing.
What does the put/call volume and open-interest ratio tell me about RMBS?
Elevated put/call ratios and shifts in volume-to-OI often precede or confirm moves. TECHi surfaces realtime and historical ratios alongside the full chain so you can separate noise from actionable flow — a core signal layer inside the Forward model.
Why does TECHi show the complete Greeks table instead of just prices and IV?
Greeks are not decorative. They are the language of how options positions react to price, time, and volatility. TECHi exposes the full suite because these numbers are the actual inputs that drive quant signals and Forward scenario outputs.
Is the RMBS options chain real-time or a snapshot?
The displayed surface is the latest available historical snapshot from the provider, timestamped. Live execution prices can differ by venue and millisecond routing — always verify inside your broker before trading.
What happens when no options chain is available for RMBS?
TECHi shows a clean unavailable state rather than fake data. Forward conviction does not disappear — the model continues to synthesize price action, news sentiment, technicals, and any available flow signals from the rest of the RMBS quote stack.
