Ping vs latency vs jitter in trading, what is the difference?
The short answer
This page explains three words you meet when a connection drops or an order is late. Knowing which one is high shows where to look. Ping times data going there and back, latency is the delay your orders meet, and jitter means uneven delays.
Ping, latency and jitter point to different causes of a slow screen.
These three words describe three different things. Mixing them up can send you looking in the wrong place when your connection drops or an order is late.
The table puts them side by side, with what each one means on your screen.
| Term | What it is | The question it answers | What it means for you |
|---|---|---|---|
| Ping | A tool that sends a small piece of test data and times the reply | How long does a test take to go there and back? | A number you can check yourself, but not the time your order takes |
| Latency | The delay your platform’s data meets on the way to your broker | How long does the data take to arrive? | How long your order takes to land, so how far the price can move first |
| Jitter | Uneven delays, how much the delay changes from one reading to the next | How steady is the delay? | A price can arrive late one moment and on time the next, so your chart jumps |
Latency and jitter describe the path your data takes to your broker. Ping is one way to look at both. The what is trading latency page covers where the delay comes from.
A ping number is a guide, not the time your order takes.
Ping sends a small piece of test data to another computer and times the reply. Your platform’s trading data is a different kind, and a server can treat the two differently.
So the delay your platform meets may not match the number ping prints. One reading shows one moment, so run ping for a while before you trust it.
Uneven delays make a chart jump, even when the average looks fine.
Jitter means the delay changes from one reading to the next. So a price can arrive late one moment and on time the next, which makes a chart jump.
The internet standards body prefers the name delay variation, because different groups use jitter in different ways. This made-up example shows why an average alone can fool you.
| Measure | Connection A | Connection B |
|---|---|---|
| Five readings | 48, 50, 49, 51, 52 | 20, 85, 30, 80, 35 |
| Average | 50 | 50 |
| Lowest and highest | 48 and 52 | 20 and 85 |
| Spread (highest minus lowest) | 4 | 65 |
| Average change from one reading to the next | 1.5 | 53.75 |
The readings are made up to show the idea. The spread and the change between neighbouring readings are rough guides.
Both connections average 50, so the average cannot tell them apart. Connection A stays close to it, and Connection B swings by tens. That swing is jitter.
An average can look fine while the readings swing. If your platform hangs at moments while your average looks normal, look at the highest readings, not the average.
Distance sets a minimum that no reading can go below.
Distance sets the least time data needs to go there and back. Uneven delays are extra waiting on top of that minimum, often when a network on the path is busy. The panel below works out the minimum for any two of our cities.
The maths of ping
01
Your broker’s distance sets a minimum time for every order
Light in a cable travels about 200 km every millisecond. Your order goes there and back, so every 1,000 km adds at least 10 ms.
What it means for youPhysical distance dictates your latency floor. Fibre travel times remain constant regardless of routing tools.
minimum there and back (ms) = distance (km) ÷ 100
02
One lost piece of data makes everything wait
When a packet drops, your platform pauses while requesting a retransmission across the full distance. Consecutive drops double this waiting penalty. Incoming price ticks stall during the exact seconds volatility peaks.
wait 1× → 2× → 4× → 8×
03
Our server in your broker’s city recovers lost data locally
Our server in your broker’s city opens the final connection to your broker. On a quiet connection, a repeat loss doesn’t double the wait.
What it means for youWhen a piece is lost near your broker, our server recovers lost data inside that city instead of from your computer.
distance set by physics · recovery in your broker’s city is ours
Try your own distance
Singapore to London is about 10,850 km in a straight line, so at least 108 ms there and back. No order can reach your broker and hear back in less. Real routes are longer.
We don’t promise lower ping because distance sets the minimum. Local recovery in your broker’s city covers only the connection between our server and your broker. The repeat-loss fix covers the first few tries on a quiet connection, after the first repeat try.
If your lowest reading sits close to that minimum, distance is most of your delay. Only moving your platform nearer your broker shortens it.
Your own readings show whether distance or a busy path slows you.
Ping your broker’s server about 30 times, in a busy hour and again in a quiet one. The guide to checking ping to your broker explains how. Note the lowest, average and highest readings, and any lost replies.
The lowest reading is your connection at its best. Readings above it point to data waiting in line on a busy network.
Match what you see to a likely cause in this table, so you fix the right thing.
| What you see | What it points to |
|---|---|
| Every reading is high and close together | A long distance, a long delay, not uneven delays. Only a platform nearer your broker shortens it. |
| The average looks fine, but the highest readings sit far above the lowest | Uneven delays, with a busy path as one cause. Your chart may jump at those moments. |
| Every reading looks fine, and your platform still hangs | A delay that ping does not measure, such as your broker’s systems or your platform. Look there next. |
Your own results decide whether a long delay or uneven delays matter more.
It depends on how you trade. The standards cited here define the terms and do not rank them.
Compare each with your own results. Note the times something looked wrong, then check your ping readings from the same times. If they were steady, look elsewhere first.
The latency and jitter guide goes deeper into both.
Our server recovers lost data inside your broker’s city, not lower your ping.
A backtest runs on your own machine, so no internet link can lose a piece of data during a news release. In live trading, one lost piece holds up every price update and order behind it. Everything waits while your computer sends it again across the world.
Our server in your broker’s city opens a separate local connection to your broker. If data drops on that link, our server recovers it inside that city.
When data drops near your broker, your order waits on that short local link. Trading ports go first when a server is busy, and broker addresses stay warm in memory.
Data lost between you and our server is recovered between those two. We don’t promise lower ping. Distance sets the minimum. We make no claim about uneven delays.
You cannot paste four values into your platform while your chart is already frozen in a live trade. Set it up today while the market is calm. Then time it on your own screen during the next release.
A ping test runs outside your trading app, so it never goes through us. It reads the same with or without Traders Proxy. To compare, time your platform itself, without us and then with us.
If our server in your broker’s city is unreachable, your platform shows an error and your dashboard asks before using another city. If your broker prohibits proxies, don’t use one.
Frequently asked questions
What is a good ping for forex trading?
There is no agreed cut-off, so we quote none. Log your own ping at the hours you trade and compare it with your results. If it looks high, read about high ping to your broker.
What is acceptable jitter for trading?
We know of no agreed cut-off, so we quote none. Watch whether your readings stay close together over a busy session, and whether trouble lines up with the wide ones.
Is ping the same as latency?
No. Ping times a piece of test data going there and back. Latency is the delay your platform’s own data meets, which ping estimates but may not match.
Why does my ping look fine when some moments are slow?
An average hides the swings, and two connections can share an average and still differ in jitter. A busy path is one cause. See why ping changes at certain hours.
How do I weigh a claim about ping or jitter?
Ask what was measured, on which connection, when and how often. One reading shows one moment, so look for a method you can repeat yourself.
Does Traders Proxy reduce jitter?
We make no claim about jitter. Instead, our server in your broker’s city opens a local connection to your broker and recovers lost data inside that city.

cTrader drops and re-logs in on a loop (Disconnected, Slow connection or Connection failed)
“Update: Dropouts seem to be entirely due to my wifi adaptor. When plugged direct into the router no problems.”
What our system reduces. Traders Proxy gives your platform its own route to its servers, which can help when your provider's route is the weak stretch. It does not fix your own Wi-Fi or router.

HTTPproxy loginPrimary
Where it stops. Helps only when your provider’s route is the weak stretch. It does not fix Wi-Fi, router drops or Spotware faults, and cTrader uses HTTP only.
Connecting Telegram when your network blocks direct access
“ProtonVPN, Surfshark, NordVPN”
What our system reduces. Telegram in one tap on every plan. Telegram’s own proxy type is included on the 2-device and 5-device plans.
- Telegram in one tapPrimary
Where it stops. Telegram in one tap on every plan, plus Telegram’s own proxy type on the 2-device and 5-device plans. A network that inspects traffic can still block it.
Workplace, library or other managed network lets the web through but not MetaTrader
“I keep getting the message "Proxy test failed" no matter what proxy settings I try to set.”
What our system reduces. If a network blocks your platform's direct connection to your broker, our server can make that connection for you, as long as your network lets you reach our server.

SOCKS5loginPrimary - Own separate connection to your brokerPrimary
Where it stops. Many workplaces, libraries and campuses allow only web ports or block proxies altogether, and we can't tell in advance. Check your network's rules first, as using a proxy against an employer's policy is your call and risk. The Try plan is the way to test.
Remote desktop is laggy on a Mac or a very wide screen (client-side rendering, not distance)
“Try reducing the resolution on the remote session. Drop it down to 19220 x 1080 and see if that helps.”
How local trading avoids it. Your platform runs on your own computer, so there's no remote-desktop window to lag.
- Platform stays on your own computerPrimary
Where it stops. Needs a version of your platform that runs on your computer. Anything you still reach by remote desktop is as laggy as before.
