Searching for profit that survives costs
1,105,920 unique configurations in this batch; 352 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: 8.1%. This annualized figure describes the historical raw-price simulation.
All settings were tested for 6 fixed rule sets in the declared grid. The maximum is proven only within that finite historical grid. Full and recent-period results were used to select finalists, so those returns are in-sample. No global maximum across all possible strategies has been established. Corporate-action adjustments remain incomplete.
Does the winner survive small changes?
Stops and maximum holding periods varied by ±10% and ±20%. 25/25 nearby settings also had positive recent stress returns. Nearby full-history NAV ranged from ৳262,794 to ৳443,253. This is parameter sensitivity on the same historical data, not independent validation.

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.
The trade count–profit frontier
These 72 grid candidates cannot be beaten on both historical NAV and completed positions by another grid candidate. More positions often reduce profit.
