What the tabs are
Open the simulated Risk lab on /t/btc/strategy. Catalog: starting structures. Builder / Risk lab: legs, spot, vol, T+0 and expiry payoff, simple PoP-style stats. Positions: research positions you log — not broker fills. Library: saved structures for free members (caps apply).
If a number came from a mock chain, the payoff is a cartoon of a cartoon. Check the banner.
Build a vertical once
Add a long lower-strike call and a short higher-strike call (bull call). See max loss ≈ debit × multiplier, max gain ≈ width − debit. Change IV and spot to see T+0. That single habit teaches more than ten threads.
Then clone as a put spread. Then an iron condor. Always look at the unrestricted side so you never accidentally build a naked short.
Saving and sync
Signed-in free accounts sync a limited number of structures and ideas. Guests store locally on this browser. Export/import is for your files, not a share-to-twitter live book.
Account hub lists the same libraries. Deleting in one place should be treated as gone.
What Risk lab will not do
No routing, no margin from your venue, no liquidation engine, no tax lot. Fees are illustrative if present. PoP is a model on implied or assumed vol, not a promise.
When you are ready to trade, you re-enter the legs on the venue — or you do not trade.
From lab to Match
If the structure needs listed weeklies on SOL, confirm a venue lists them before you fall in love with the payoff. /v and /find-venue. If it needs combo tickets, check product flags.
This is the intended SEO loop: learn → simulate → pick a venue.
Practice
/t/btc/strategy, /chart/BTC for spot context, then /guides/vertical-spreads. Educational simulator only.
Not an order ticket.
