Harwinder Sekhon 44cadf7a9f Data provider: key from config.json/env, provider registry, drop hardcoded key
Resolves the Twelve Data API key through app_config.provider_api_key()
(env → config.json → no default) instead of a hardcoded field on
PlatformConfig. Adds data_provider.PROVIDER_REGISTRY + make_data_provider()
so signal_aggregator and the backtester build the active provider through
one seam; telegram_bot.py gets the same one-line WS-key fix now (per Task 4's
already-planned edit for that line) so the suite doesn't crash on import
between this commit and Task 4's full wiring pass.

ForexBot2 — GPU-Accelerated Backtester
======================================
Replays historical OHLCV bar-by-bar through the live SignalAggregator so
backtest results are identical to what the production scanner would have
generated. Pre-computes all indicator series with CuPy/NumPy on the full
dataset (causal, zero look-ahead) and looks up values per bar instead of
recomputing each time — giving a 100x+ speedup over a naive replay while
preserving the exact signal logic.
Key properties:
- Uses real SignalAggregator.analyze_from_dataframes (same gates,
same XAU strategy hooks, same trade setup math).
- News engine disabled (use_news=False) — backtests are pure technical.
- Session filter, MTF agreement, regime classification all flow from the
bar timestamp, never datetime.now().
- XAU weekend/weekday filter applied here (analyze_from_dataframes skips
it; only analyze_pair enforces it in live mode).
- Trade simulation is full candle walk on the primary timeframe using
High/Low; if both SL and TP1 hit in the same bar, SL is assumed first
(conservative).
- Ships with CuPy fallback to NumPy so the script runs anywhere.
Usage:
python backtest/gpu_backtest.py --pair XAUUSD --days 365
python backtest/gpu_backtest.py --pair XAUUSD --start 2025-01-01 --end 2025-06-01
python backtest/gpu_backtest.py --pair XAUUSD --days 180 --no-cache
