What Most Traders Don't Know About Order Execution

Your chart doesn't decide your profit. Your execution does.

Here's what traders rarely understand:

1. 1

   Your order becomes information

   The moment you place a large market order, the system knows it. Liquidity providers adjust spreads, algorithms react, and slippage happens.

2. 2

   Market orders are the most expensive orders

   They cross the spread → instantly pay a hidden tax. Retail traders underestimate this cost — but quants design entire systems to avoid it.

3. 3

   Volatility amplifies execution errors

   During high volatility, spreads widen, order books thin, fills become chaotic, duplicate trades slip in. This is why automation with risk guards massively outperforms manual execution.

4. 4

   A good strategy is useless without good execution

   Pros say: "Half the edge is execution." And they're right. If your strategy is good but your execution is sloppy, you've already lost.
