Order type
Limit orders only
There are no simulated market orders that can ignore the displayed options spread.
Mayospell has a working simulated options ledger, but no live brokerage rate card yet. This economics contract shows current simulated charges and fills, every cost a live options account must disclose, and the evidence required before Mayospell can claim low commissions.
Current claim status
No live low-commission claim
The simulator captures the bid-ask spread through executable-side fills. It does not yet debit separate commissions, exchange fees, or statutory charges, so its P&L is not live-cost complete.
Mayospell economics snapshot: August 19, 2026. Simulation contract published; live rate card not launched.
Subscription, software, data, simulation friction, and any live execution are different cost rails. Combining them into one vague fee number would make comparison impossible.
Mayospell does not currently advertise low live commission rates. Broker, exchange, clearing, regulatory, data, platform, exercise, and assignment costs must be contracted and published before live brokerage execution can be offered.
These behaviors come from the current Mayospell options simulator. They are useful product evidence, but they are not a substitute for broker routing or production market-data validation.
Order type
There are no simulated market orders that can ignore the displayed options spread.
Buy fill
A buy cannot fill at the midpoint merely because the limit crossed the market.
Sell fill
Closing value is tied to executable-side liquidity instead of an optimistic midpoint mark.
Quote freshness
The simulator freezes or waits rather than manufacturing a trade from an old quote.
Position mark
Long-option equity starts from a liquidation-side mark, while missing or stale telemetry remains visibly qualified.
Explicit fees
Simulator net P&L is not yet commission-complete and must not be marketed as live net performance.
An options prop firm cannot prove low commission rates with a broker headline alone. The rate card has to expose all recurring, transactional, and lifecycle costs that can change net P&L.
Let C equal commission per contract side, E equal exchange, routing, and clearing charges, and R equal regulatory charges. These formulas stay variable until a live Mayospell rate card exists.
Spread cost is economic friction but not a separately invoiced fee. It must still be measured alongside commissions because options spreads can dominate small-target and 0DTE strategies.
Launch gate
This gate turns “options prop firm low commission rates” from marketing language into an operating requirement. A launch remains incomplete if any material charge or execution assumption is missing.
Name the executing broker, clearing relationship, supported option classes, and account ownership model.
Publish an effective-dated fee table for every contract side, venue pass-through, regulatory charge, and minimum.
Show professional and non-professional data pricing, OPRA entitlement, depth add-ons, taxes, and proration rules.
Document exercise, assignment, expiration, corporate-action, hard-to-borrow, and exception handling before the first live trade.
Run matched simulated-versus-broker fill tests and report spread, latency, partial-fill, rejection, and slippage behavior.
Display gross P&L, every cost line, and net P&L in the ledger, payout review, statement, export, and dispute packet.
Version the rate card and notify traders before changes take effect; never overwrite the terms attached to a historical fill.
The cheapest-looking rate can become expensive once contract sides, spread, data, platform, exercise, and assignment terms are included.
No live-rate claim is supported today. The current Mayospell options lane is simulated, and its ledger does not yet deduct a separate per-contract commission or statutory fee. A low-commission claim requires a named broker relationship and a public all-in rate card.
They currently have no separate commission debit, but they are not frictionless. Marketable limit buys fill at the fresh ask and sells at the fresh bid, so the bid-ask spread affects the account. That still does not make the simulator commission-complete.
C is the broker commission charged for each contract side. E is the exchange, routing, and clearing total for the order. R is the applicable regulatory total. The symbols remain variables until Mayospell has contracted, effective-dated live rates.
It may. Professional and non-professional data entitlements can differ, and a real launch must publish OPRA, exchange-depth, platform, tax, proration, and cancellation terms before checkout or live promotion.
Compare all-in cost for the structures and size you actually trade. Count every contract side, then add spread, broker commission, exchange and routing fees, regulatory and clearing charges, data, platform, exercise, and assignment costs. A headline per-contract rate alone is incomplete.
No. It can prove deterministic limit-order behavior, fresh-quote gating, isolated ledgers, and auditable simulated fills. It cannot prove production OPRA capacity, broker routing, partial fills, live latency, price improvement, or live net economics.
Pricing, execution, integrations, and live promotion each own a different part of the economics contract.
Separate the 30-day account subscription, activation path, recovery costs, and software add-ons from trade-level economics.
