Market orders are convenient. They are also the most expensive habit in trading.
Taker vs maker fee on most futures pairs is roughly double - you pay that premium every time you want an instant fill.
Three habits that quietly cut your fee bill: 1. Default to limit orders when entry timing is not critical. 2. Batch small entries - ten tiny market orders cost more than two planned ones. 3. Know your effective rate - what you pay after rebates and payback, not the sticker rate. Most traders have never calculated it.
The sticker fee is not what you pay. The effective fee is.
