## How to use

Enter the position with query parameters. Option legs are `legs[N][field]`, N counting from 0, up to 4 legs ([subscribe](https://www.optionistics.com/subscribe) for 8): `expiry` (YYYY-MM-DD, required), `strike` (required), `putcall` (C or P), `side` (long or short), `quantity` (contracts, 1-1000), `cost` (entry price per share; default the contract's theoretical price), `ivol` (volatility override, decimal), `hidden` (1 leaves the leg out of the totals and chart). A stock leg: `stock[side]`, `stock[quantity]` (shares), `stock[cost]`. Or start from a `preset`: bull-call, bear-call, bull-put, bear-put, straddle, strangle, covered-call, covered-put, calendar-call, calendar-put, diagonal-call, diagonal-put, single-call, single-put. Pricing: `rate` (percent), `model` (a American, e European; default American when a dividend is set), `voltype` (0 slider, 1 indexed IV, 2 historical IV, 3 each leg's IV), `ivSlider` (1-400, with voltype 0), `dividend` (next dividend, dollars), `exDate` (YYYY-MM-DD), `frequency` (0 none, 12, 4, 2 or 1 a year). Chart: `solveFor` (p price change, dl days left), `factor` (price range either side of the stock price, 0.01-1, default 0.5), `dateOffset` (price change: value on the report date plus dateOffset + 1 days; default -1, the report date), `sliderPrice` (days left: the stock price to value at).
