Each candle is one 1D bar: the thin line is the high-low range, the thick body is open-to-close. Vertical marks show when the trade opened and closed. One real trade, picked by recency — an illustration of the executed rules, not proof they will work again.

How $10,000 would have changed

The account balance after each closed trade, starting from the stated budget.

  • Account value

Left axis is dollars, bottom axis is time. The line only moves when a trade closes, so flat stretches are periods the rules stayed out of the market.
