Rebuild under newer Xcode, add link to new OptiViz app.

Add option to specify a simple moving average length to control how the start point of the drift / diffusion forecast is set.

Color code validate backtest metrics.

Fix crash when re-computing validation run to a longer day count.

In the exhaustive Validate tab, add the ability to drag back by slider on the top toolbar to dynamically examine earlier days within the original fixed investment horizon but using the same validation result. For example, if you had validated a 21 day forecast for 200 days, you can slide the slider backwards to also check 20, 19, 18, ... 1 days using the same validate session, without having to recompute the validation for each sub-horizon. The total validation days are decreased dynamically when you drag back the slider, because there is no pre-computed data for those cases. For the above example, if you had set the slider to a 20 day investment horizon with original full horizon being 21, it would only show 199 days of validation, because that is all that was computed during the validate process. Validation risk band graphs (1,5,50% etc) are redrawn for the new dynamic horizon and truncated to indicate the shorter effective validation, and validation metrics along with backtest residual metrics are also recomputed for the smaller dynamic forecast horizon. Please let us know in the app reviews if you find this feature to be useful!

Update stochastic volatility formulation to make it less sensitive to the rho correlation parameter.

Add bring your own polygon.io key feature like on macOS version to allow stock market data to be pulled and analyzed again. Sync w/ macOS code base. Update to newer version of Xcode and iOS environment. Slight user interface adjustments for newer versions of iOS.

Alert to tell the user that we only support crypto assets at the moment due to the shutdown of a data provider.

Compute backtest residual as fraction of 50th percentile forecast instead of absolute dollars, for more realistic application in cases where actual asset price swings are large over time.

Add market holidays for 2025 and 2026 for forward forecasts into the next years.

Allow larger monte carlo run counts without hitting memory limits and crashing. Sync up with macOS version. For larger Monte Carlo run counts, try the multi CPU option located on the upper right of the Monte Carlo tab screen and take advantage of the latest M1, M2, M3, or M4 multi-core CPUs in your fancy new iPad! This is especially useful for long backtests.

Add link to new ML macOS app. Options data message. Add pop up alerts for pop tech articles regarding this app. Add additional percentiles to the summary report on the Monte Carlo screen.

Sync up user interface changes from macOS Intel version, additional small UI adjustments. Rebuild on newer XCode per Apple requirements.

Update market holiday calendar through 2024 for more accurate date report-outs for forecasts involving stocks & ETFs (e.g. translating trading days forward into a calendar date).

Add support for FTX token (symbol FTT). Sync up code base with macOS version.

Allow actual $ blue curve to be toggle-able on/off on the validate plot.

1) speed up Validate to realized 50th percentile, which is a more detailed computation, 2) allow user to toggle curves on/off on the Validate Plot by tapping on the corresponding legend. Allow user to toggle the residual data hash marks as well.

Provide a slider to control which put/call options (bars or bubbles) are displayed, filtering by expiration date. Default is all expiration dates in the modeled time period (marked "all expiry" to the right of the slider). Moving the slider lets you select single expiration dates to display. This can be useful when viewing the envelope model along the time axis via the "circle t" button, because in that case, graphics for all expiration dates are displayed on top of one another. While it is sometimes useful to see such overlaid graphics, isolated versions may be useful as well.

Allow put/call options chain data (price, open interest, and price * open interest) to be shown in 3D bar chart form instead of as bubble plots, as an option. This makes it easier to view when there is a lot of data in the chain. Add a view option "along time axis" (circle t icon) to see these bar charts flat to the screen. Closer expiration dates are shown with more solid colors, farther expiration dates are shown more transparent. Similar color coding is used for put/call distinction as for the bubble plots.

Ticker symbol button help popup. Caution user if he switches correction on without first having went through the predictor-corrector steps.

User interface refinements.

User interface tuneups.

Add support for more crypto coins: SOL$ DOT MATIC TRX$ AVAX WBTC LEO$ UNI FTT CRO LINK$ NEAR$ ATOM$ ALGO APE FLOW VET$ FIL ICP MANA SAND$ XTZ HBAR AAVE THETA QNT The dollar signs following some symbols are to distinguish them from stocks of the same symbol. E.g. SOL$ is Solana crypto.

Sync up iPad version with mac version. New icons on tab bar.

Match up to the macOS app by adding forward Sharpe and Sortino ratios, and the standard deviations of returns that feed into them.
