bruedemo

Internal TEST build of the Brue trading-strategy language engine (pure Python). Published for real-world install testing by the London Strategic Edge team only. The engine will be republished under its final name; do not depend on this package.

A complete strategy is a few precise lines. The header is config only; names are optional and unnecessary:

strategy(capital=100000, default_qty=0.25)

fast = ema(close, 12)
slow = ema(close, 26)

if crossover(fast, slow):
    entry("long", stop_loss=close - atr(14) * 2)
if crossunder(fast, slow):
    close_all()

Run it in one line:

import brue

r = brue.run("trend.brue", "EURJPY_1h.csv")
r.stats          # winRate, profitFactor, sharpe, drawdown, ...
r.trades_frame() # the ledger as a pandas DataFrame

Fills are honest (orders fill at the NEXT bar's open; a stop beats a target inside one bar), 143 indicators are built in, and python -m brue adds montecarlo / walkforward on the same script.
