Execution essentials

How available buying and selling interest determines fill quality, spreads, and slippage — and why low liquidity hurts bots most.
Market execution
What actually happens after you click buy, the difference between market and instant execution, and why fills can differ from the quoted price.
Bigger accounts
Why larger positions can receive worse average fills, what market impact is, and how account size interacts with available liquidity.
VPS
How a low-latency VPS located near the broker reduces execution delays, helping orders reach the market faster and more consistently.
