Percentage-based size rounds down to zero on small accounts
Steps: Set size as a small percentage of account, trade a high-priced instrument on a small balance.
Expected: Either the minimum tradeable quantity, or a clear message that the computed size is below one unit.
Actual: Size computes to zero and the signal is skipped with no explanation. From the outside it looks like the strategy didn't fire.
Impact: I assumed my entry conditions were wrong. They weren't.
