Know the mechanism
A stop-loss is intended to close exposure after an adverse price condition occurs. Depending on the instruction, it may activate a market order or another specified order type. A stop-market instruction generally does not guarantee the trigger price as the final execution price. A stop-limit instruction adds a price boundary but can fail to execute. Understanding that difference is essential before treating either as a fixed monetary loss ceiling.
Read the contract and monitor changes
Check the reference quote, valid sessions, quantity and behavior after amendments or partial fills. Keep an acknowledgement when the instruction is changed and review the resulting exposure after execution. FYLU has not published live stop handling or an account protection policy. Its preview cannot place a stop or verify that one remains active, and educational examples do not establish a guaranteed exit or compensation for a market gap.
