## What it is

TradingTune is an independent browser extension for Chrome and Brave (Chromium,
Manifest V3). It is not affiliated with, endorsed by, or sponsored by
TradingView, Inc. It injects its own panel into TradingView's strategy settings
dialog, sets strategy inputs, triggers TradingView's own backtester, and reads
the results, all locally in your browser. For each input you tune you give it a
range (minimum, maximum, and step). One optimization cycle runs one backtest of
one parameter combination.

## The seven optimization methods

TradingTune ships seven search methods. It auto-selects one based on how many
parameters you have enabled; you can override the choice at any time.

Auto-selected by enabled-parameter count:
- Brute Force: exhaustive grid sweep of every combination; guarantees the best
  result within your ranges, only practical for small spaces. Auto-selected when
  3 or fewer parameters are enabled.
- Simulated Annealing: a probabilistic walk that explores widely, then settles
  toward an optimum as it cools, so it can escape shallow local optima.
  Auto-selected when 4 to 10 parameters are enabled.
- TPE (Bayesian): Tree-structured Parzen Estimator, a Bayesian sampler that
  models which settings work and spends cycles where the payoff is most likely.
  It is the default for new strategies and is auto-selected when 11 or more
  parameters are enabled.

Never auto-selected (choose them manually):
- Bisection (Smart Search): a fast, deterministic, resumable search that
  brackets the best region with a coarse sweep, narrows with golden-section
  steps, then polishes the top values.
- Bisection then TPE Refine: runs the full Bisection search, then hands the
  remaining cycle budget to TPE to refine around the discovered peak; the
  highest-effectiveness method of the seven.
- Sequential Improvements: coordinate descent that tunes one parameter at a time
  in round-robin; cheap and easy to read, but blind to parameter interactions.
- Random: uniform independent sampling each cycle; no memory, a surprisingly
  tough baseline, and the warm-up that bootstraps TPE.

## Worked backtest examples

All examples optimize the founder's own private strategy (the Smart Momentum
Grid) on the daily (1D) timeframe and compare it against buy-and-hold on the
same asset over the same period. They are the founder's own strategy, shown only
to illustrate what the software does: hypothetical, historical, not for sale,
not a recommendation, and not representative of typical or expected results. Past
performance does not guarantee future results. TradingTune is a software tool,
not financial advice; it sells no strategies or signals.

- NVDA (NVIDIA, NASDAQ), TSLA (Tesla, NASDAQ), AAPL (Apple, NASDAQ), and BTC
  (Bitcoin). Each detail page shows the full TradingView metric table.

These examples each show a 100% win rate with 0 losing trades. That is a property
of the strategy design, not a promise of a flawless edge: the Smart Momentum Grid
is a grid strategy that runs without stop losses, scaling into a position and
closing a trade only once it is back in profit, so every closed trade is a win.
The real risk shows up as drawdown and open exposure, not as losing trades, which
is exactly why a 100% win rate is a flag to investigate rather than a guarantee.

## Pricing

- Free: $0. Up to 10 optimization cycles per day. A free account and sign-in are
  required to run optimizations.
- Pro: $29 per month, $299 per year, or $599 one-time for a lifetime plan. Pro
  removes the daily limit (unlimited optimization cycles per day).

## Data model and privacy

- Sign-in uses Firebase Authentication (a Google service), which issues your
  account an identifier.
- The only data that leaves the browser is your account ID and your daily
  optimization-cycle count, which sync to a Google Cloud Run function that
  stores them in Google Firestore, solely to enforce the free daily allowance.
- Your strategies, parameter ranges, optimization runs, and results stay in your
  browser's local extension storage and are never uploaded.
- No TradingView API keys are used or required.
