Symptom: The backtest sells instantly at the delist price. In reality, when a stock is broken, it often halts trading. You cannot sell. Fix: Modify your Brokey CBI to impose a random slippage of 50-100% on delisted trades. Or, treat the position as zero – you lose all capital and cannot exit. brokey for amibroker
