I’ve noticed that broker spreads seem to widen when volatility spikes, which makes sense from a market perspective. But I’m trying to understand how much spreads actually change and whether this is predictable enough to factor into my broker choice.
The question I have is: do all brokers handle volatility the same way, or do some hold their spreads tighter than others during chaotic periods? I’m wondering if comparing spreads during calm markets tells you anything useful about how a broker will perform when things get crazy.
I’m also trying to figure out if rebates account for spread volatility or if cashback is calculated on a fixed basis regardless of market conditions. That seems like it could significantly affect my actual cost per trade during the times when costs matter most.
Another angle I’m curious about: are there brokers known for maintaining tighter spreads during volatility, or is this more of a lottery where execution quality just depends on the day? I want to know if this is something I can actually analyze or if I should just assume all brokers will widen spreads when markets get messy.
Do any of you have real data on how spreads behave for specific brokers during major market moves?
Spreads widen everywhere during volatility. ECN brokers widen less.
Test actual spreads during news not calm markets.
Spread behavior tells you a lot about broker architecture. Market makers (STP) widen spreads more during volatility because they’re holding risk. ECN brokers widen less because volatility is just more volume through the network.
This is measurable. Open two broker platforms side by side during a major news event and watch EUR/USD spread. A broker that holds 1.2 pips while others jump to 2.5 pips has better infrastructure or inventory management.
Rebates are typically calculated on the spread they charge, not a fixed amount. So if spreads widen during volatility, your rebate amount also changes proportionally. Most cashback services track and credit based on the actual spread charged.
For comparing brokers: test spreads on calm days, then deliberately trade around economic announcements and watch them again. The brokers with minimal spread widening during volatility are usually more reliable overall. It’s a reliability indicator.
I’ve noticed that XTB’s spreads stay pretty consistent even during news events. They might go from 1.0 to 1.4 pips on EUR/USD but some other brokers jump to 2 or 3 pips.
That makes a real difference if you’re trading frequently. When spreads widen that much, your rebate also gets calculated on a wider spread, which works in your favor in some ways but obviously you’re losing money to the wider cost.
I try to avoid major trades right at news time anyway but knowing which brokers hold spreads better means I can be a bit more flexible with timing.
All brokers widen spreads during news. Some widen more than others.
ECN brokers tighter than market makers during volatility.
I’ve tracked spread behavior on five different brokers over about eight months and gathered some real data on this.
All brokers widen spreads during major volatility. No exception. But the amount varies significantly.
Market makers usually widen spreads 150-250% during volatile news. ECN brokers often only widen 50-100%. This is because market makers are holding inventory risk while ECN brokers are just passing orders through a network.
The interesting data point: the brokers that widen the most during volatility also tend to have execution issues like slippage and requotes. That’s because their backend infrastructure is struggling with the volume.
For your calculation: if you assume your rebate gets credited on the wider spreads, yes, volatile periods lower your net benefit. A 0.5 pip rebate on a 1.0 pip spread is better than a 0.5 pip rebate on a 2.0 pip spread, obviously.
XTB spreads during volatility: they’re mid-range. Not the tightest but not terrible. Typical expansion is maybe 80-120%. I’ve seen worse from other brokers.
One practical thing: if you’re a scalper or high-frequency trader, spread volatility matters way more than if you hold positions for hours. Test a broker’s specific spread behavior during news events before funding.
I set up a spreadsheet and logged spreads every 30 seconds for one hour around three different major news events. That’s all it takes to see which brokers are reliable during volatility versus which ones spike.
