What is high volume trading and how does it differ from retail trading?
High volume trading involves placing large trade sizes or frequent orders, often using institutional-grade execution. Unlike retail trading, it emphasises ultra-low costs, deep liquidity, and reliable fills to maximise efficiency when moving significant capital through the markets.
What do high volume traders need in a broker?
High volume traders require brokers offering raw spreads, transparent commissions, and rebates that scale with activity. Execution speed, minimal slippage, and deep liquidity pools are essential, alongside strong regulation to ensure capital safety when trading at size.
Is high volume trading more profitable — or riskier?
High volume trading can increase profits through lower per-trade costs and rebate benefits. However, risks scale equally—large positions amplify losses, while execution delays or slippage can be costly. Effective risk management and strong broker infrastructure are non-negotiable.

FAQs
Do high volume traders get better leverage limits in the UK?
No. FCA rules cap retail leverage at 30:1 regardless of trade size. High volume professionals may access higher leverage only if they qualify as “elective professional clients” under FCA criteria.
Are there tax implications for high volume trading in the UK?
Yes. Profits from CFD and forex trading are generally subject to Capital Gains Tax, not income tax. High volume traders may need professional advice to optimise tax efficiency and remain compliant.
Can high volume traders use multiple brokers at once?
Many do. Splitting trades across brokers reduces counterparty risk, increases liquidity access, and can secure better pricing. However, it requires efficient capital allocation and strong risk controls to manage multiple accounts effectively.
What technology do high volume traders typically use?
They rely on low-latency VPS hosting, direct market access (DMA), and trading APIs for speed and stability. Advanced charting, risk management tools, and custom algorithms are often used to manage scale and execution precision.
How do rebates really benefit high volume traders?
Rebates return part of the commission or spread cost once certain volume thresholds are met. For high volume traders, these can significantly reduce effective trading costs, improving profitability even with slim per-trade margins.
