Previous-day high/low breakout on gold, 2016-2026 (RoboXpert, 31 October 2026)
Guide: https://roboxpert.ai/en/guides/previous-day-breakout-gold/

simulate.py   the reference rule and the simulation (Python 3 with numpy)
results.json  every number in the guide: yearly and total R per variant and cost scenario,
              the minute-period trades (date, side, R) and the example day
plot.mjs      draws the three figures from results.json (Node.js with sharp)

Price data is not included. simulate.py expects two files in the folder named in PDB_DATA:
bars_XAU_IC_L.npz (hourly bars) and bars_XAU.npz (minute bars), each with the arrays
t, o, h, l, c (bar time in broker server time UTC+2/+3 as seconds, mid prices).
We used IC Trading hourly bars 01/2016-08/2022 and BlackBull minute bars 09/2022-10/2026.

Hypothetical simulation. Not a trading recommendation and not a test of any product.
