Tequila Market

Описание: A real-time stock charting web app for U.S. and Korean markets, built with
Flask and TradingView's lightweight-charts. It loads historical OHLC bars
from a local SQLite cache (with incremental top-ups from the KIS REST API for
the last day plus today's live bar), making chart loads ~30× faster than
direct API fetches while keeping today's candle live via a 5-second polling
updater. The chart layer renders fully recomputed technical indicators — six
moving averages (SMA, SMMA, EMA), Bollinger Bands, MACD and RSI in
synchronized sub-panes, Ichimoku cloud, a Kalman-filter trend line, and
regression-based support/resistance — all toggleable per chart or per tile. A
1×N / 2×2 / 2×3 grid mode lets you watch several tickers side-by-side with
independent indicator state, and a yfinance fallback (with on-disk parquet
caching) covers symbols not in the local DB.
