Using the wrong order type can cost you money on every single trade. A market order during low liquidity might cost 3-5 ticks of slippage. A limit order at the wrong level means missed entries. Understanding order types is as fundamental as understanding candlesticks.
Understand how each order type works before risking real money
Execute immediately at the best available price
A market order fills instantly at whatever price is available. You get guaranteed execution but NOT a guaranteed price. In fast markets, you may get filled at a worse price than expected (slippage).
When you MUST get in or out NOW — closing a losing trade, entering during a breakout you can't miss, or when the spread is tight and the market is liquid.
Slippage in fast/illiquid markets. You might pay 2-5 ticks more than expected during high volatility. Always check the spread before sending.
NQ is breaking out above resistance at 18,500. You send a market buy. The best ask is 18,502. You get filled at 18,502 — 2 ticks of slippage, but you caught the move.
