crazygirl437/hyper-grid ? reverse-engineered prompt

Build me a local desktop app for grid trading on Hyperliquid perpetual futures.

I want it to let me pick a market, set a price range, grid count, size, and leverage, then preview and start a strategy that places buy orders below the market and sell orders above it. Please include Simulation, Testnet, and Mainnet modes, with a clear way to enter my private key locally for live modes, and make sure the app can pause, resume, and stop safely by canceling orders and flattening the position when needed.

Also add useful risk controls like max drawdown, daily loss limits, breakout behavior, and the option to use fixed or dynamic grids. I’d like PnL tracking, fill history, equity curves, and import and export for strategy settings. Make the UI multilingual with a language switcher, and default to the user’s system language. If you need to check current docs for Hyperliquid or the desktop tooling, look them up online first.
