Next: see how copying works in more detail
The copy trading guide covers sizing, a made-up follower against leader comparison and how to test copying before any money.
What is included
- What it is, in plain words
- The formula or mechanism, with exact arithmetic
- How it hits grid, martingale and DCA bots
- A check you can run before you switch a bot on
Who it is for
- People who run or plan to run a trading bot
- Anyone reading a backtest or a bot sales page
- Readers who want the numbers, not the pitch
- Not advice, and not a signal service
Key facts
- ZuluTrade is described here only as a type of product: a copy-trading network. Some accounts publish trades, others follow them, and a follower's account opens and closes positions when a chosen provider's account does.
- Copying is a second order placed after the first. The follower gets their own price. The gap is lag plus slippage, and it is a cost on every trade the follower makes.
- Lag hurts a fast strategy most. In a made-up example 1.5 pips of lag per trade leaves 63% of a 4-pip edge but 96.3% of a 40-pip edge (calculated by us on 31 Oct 2026, exact).
- Fees are paid whether the provider wins or loses. A made-up fee of $5 per lot on 200 trades of 0.1 lot takes $100 from a result of $500.
- Records on a network can be short, selected and survivor-only. See survivorship bias and copy trading. We do not offer signals or copy services.
What a copy-trading network is
A network of this type has two roles. A provider trades their own account, and a follower links an account and chooses providers to copy. Each trade a provider makes is sent to the followers, who each place a matching order sized by a rule. The two usual rules are a fixed size, and a size scaled by the ratio of the follower's balance to the provider's. The network usually shows each provider's history and statistics, and often a ranking. How a particular network measures, ranks and charges, and which brokers and markets it connects to, are facts that change. Read the vendor's current pages and note the date.
The ranking is where the risk begins. A list sorted by past return or by a score is a list of who did well before you looked. It does not say who will do well next, and it cannot include providers who left. Treat any ranking as a starting question, not an answer.
The general risks of copying
Lag and slippage
The follower's order is sent after the provider's, travels through a connection, and fills at whatever price the market has by then. In calm markets the difference is small. In fast markets it can be large, and the worst gaps tend to come when the provider's trade matters most, such as when a stop is hit. See slippage.
Fees and spread
A follower can pay the broker's spread, a commission, and a fee to the network or provider, depending on how the product is set up. These stack. A strategy with a small edge per trade and many trades has the least room for them. See spread.
Records that are short or selected
A provider with a strong year may be lucky, and one who lost money may have left the list. Check how long the record is, the largest drawdown and whether the statistics include trades that were closed in bulk or held open for long. See maximum drawdown.
Different size, different risk
A follower with a smaller account may reach a margin call sooner than the provider. Size rounding, minimum trade size and a different leverage can all change how the same trades hit two accounts. See margin call.
Worked example: how lag and a fee change a result
Everything here is made up. Two providers each trade a strategy. The first is fast and makes an average of 4 pips per trade before any lag. The second is slower and makes 40 pips. A follower's copy arrives with 0.8 pip of lag on entry and 0.7 pip on exit, 1.5 pips in all.
| Item | Fast provider | Slow provider |
|---|---|---|
| Gross pips per trade | 4 | 40 |
| Lag per trade (pips) | 1.5 | 1.5 |
| Pips left per trade | 2.5 | 38.5 |
| Share of the edge kept | 62.5% | 96.25% |
Calculated by us on 31 Oct 2026, exact. The same lag removes 37.5 percent of the fast edge and 3.75 percent of the slow one. If the fast provider's edge had been 1.5 pips or less, the follower would have lost on every trade the provider won.
Then add a fee
Take the fast provider and a follower with a $2,000 account trading 0.1 lot, which is worth $1 a pip. Over 200 trades the follower makes 200 times 2.5 pips times $1, which is $500. Now add a made-up fee of $5 per 1.0 lot, which is $0.50 per trade at 0.1 lot, or $100 over 200 trades. The follower is left with $400, which is 20.0 percent of the account, before tax. In this example the fee is 20 percent of what lag left.
How it hits bots
- Automated providers can show a smooth line for months and then a large loss. A follower copying a grid or martingale style takes the same tail risk, often on a smaller account. See martingale.
- Fast bots are the worst to copy, for the reason in the table above.
- Several providers at once can be one idea in disguise. If they all trade the same pairs the same way, a loss hits them together.
What to verify on the vendor's current pages
- How a follower's size is set, what happens if a trade is too small to place, and what happens when an order is missed.
- What each fee is, who charges it, and when. Note the date you read it.
- How records and rankings are built, how long they run and whether leavers are included.
- Which brokers and markets connect, and whether you can limit the loss on your own side.
- What the terms say about losses, delays and who is responsible.
- Whether a demo mode exists, and how closely its fills match live ones.
What this page does not tell you
It does not say whether the network or any provider is good or poor. We have not run it, and it states nothing about its fees, providers or users. It shows how lag and fees cut a result and how to read the evidence. The numbers are made up and nothing here is a recommendation.

FAQ
Frequently Asked Questions
What kind of product is ZuluTrade?
In general terms it belongs to the class of copy-trading networks, where followers' accounts copy the trades of chosen providers. We have not run it, so check its current pages.
Why does a follower earn less than the provider?
The follower's order comes after the provider's and gets its own price, so lag and slippage cost extra on each trade. Fees are taken as well.
Which strategies suffer most from copy lag?
Fast ones with a small edge per trade. In our made-up example the same lag kept 63 percent of a 4-pip edge and 96.3 percent of a 40-pip edge.
What should I check on the vendor pages?
Sizing rules, every fee and who charges it, how records and rankings are built, which brokers connect and what the terms say. Note the date.
Can copying lose money?
Yes. Past or simulated results are not a guide to future results. You can lose all the money you put in.
Are the numbers on this page real?
Example numbers are made up to show how the maths works, and the page says so. A figure only counts as exact when the page says it was calculated on a stated date. Nothing you enter in a calculator leaves your browser.
Can I use this to decide whether to run a bot?
It can show whether a bot's numbers hold together and how much an account can lose. It cannot say what the market will do, and it is not advice. Use it to ask better questions, then read the terms of your own broker or exchange.
Is this financial advice?
No. It is general education. All example numbers are made up and nothing here is a recommendation to copy anyone.
