What the limit controls
A buy limit sets the highest price the buyer is willing to pay, while a sell limit sets the lowest price the seller is willing to accept. The order can remain unfilled if suitable liquidity is unavailable. Reaching a displayed price does not necessarily mean every order at that level executes. Order priority, available size, session rules and the provider's execution arrangements can all affect what happens next.
Review validity and partial fills
Choose a validity instruction you understand and inspect any partial execution before replacing or cancelling the remainder. A price boundary does not remove market risk once a position is open, and a missed fill can matter if the market moves away. FYLU's information site does not submit limit orders or reserve market liquidity. Verify current specifications and execution rules with the actual service before interpreting a sample limit as an actionable instruction.
