Searching for profit that survives costs

10,790 unique configurations in this batch; 66 finalists received full and recent stress replays. Starting cash: ৳100,000. Data through 2026-10-13. Compute: local connected computer.

Full historical period: 2009-11-16 → 2026-10-13 (16.9 years). Selected finalist annualized return: 5.1%. This annualized figure describes the historical raw-price simulation.

Selection used earlier periods; 2024–2026 was replayed afterward. That period was already exposed in earlier research, so it is not a pristine holdout. No global maximum across all possible strategies has been established. Corporate-action adjustments remain incomplete.

Choose profit with more trades

Jump to the highest historical NAV that meets a minimum completed-position count. The saved frontier covers this trade-off.

Profit versus completed positions

Each dot is a finalist. Horizontal = full-history completed positions; vertical = full-history net return. Select a dot to inspect it.

Teal: positive recent stress return. Rose: zero or negative recent stress return.

NAV = cash + unsettled proceeds + marked holdings. Maximum reconciliation error: ৳1.16e-10. Normal replay: 0.44% commission plus 0.2% base friction per side, modeled impact and T+3. Stress doubles commission/base friction and uses T+5. These are research assumptions.
