How to copy MT5 trades to TradeLocker

This guide sets up one MetaTrader 5 account as the source and one TradeLocker account as the destination, then checks the copy with a test trade on demo. Count about 15 minutes. The same steps work for MT4, and for several TradeLocker accounts at once.

What you need

• The MT5 account (login, password, server) and a way to keep its terminal open: your computer or a Windows VPS. With MetaApi (beta) instead of the EA, no terminal is needed at all; see Platforms.
• The TradeLocker account: the email and password you log in to TradeLocker with, the server name (shown on the TradeLocker login screen, for example OSP-DEMO), whether it is demo or live, and its account number.
• API access on the TradeLocker side. HydraSync talks to TradeLocker from its own servers, through TradeLocker's API. Most brokers allow it; some prop firms switch it off. The connection test in step 3 tells you straight away.
• A HydraSync FX account. The 14-day trial needs no card.

What stays on: only the MT5 terminal. TradeLocker needs no app, browser tab or computer of yours.

Set it up

1. Add the MT5 account. On the Accounts page, add a MetaTrader 5 account, download the EA and copy the account's key with Copy key.
2. Install the EA in MT5. In MT5, open Tools, Options, Expert Advisors, allow WebRequest for https://hydrasyncfx.com, and turn on Algo Trading. Drag the HydraSync EA onto one chart (any symbol) and paste the key into ConnectionKey. The account shows as connected on the web within a few seconds.
3. Add the TradeLocker account. On the Accounts page, choose TradeLocker and enter the email, password, server, environment (demo or live) and account number. Run the connection test: it confirms the login and that the broker accepts API orders.
4. Create the copy link. On the Copy settings page, choose the MT5 account as source and the TradeLocker account as destination, then a lot mode (next section). The preview under the lot mode shows what a 0.50-lot trade would become.
5. Test on demo. Open a small trade on MT5 with a stop loss, move the stop, close half, then close the rest. Check each step on TradeLocker, as in Check the first copy below.

Choosing the lot size

The link decides the size on TradeLocker, not the EA. Three common choices:

Sizes are rounded to 0.01 lot. With a risk mode, an MT5 trade without a stop loss is refused and you are notified, unless the link is set to copy the exact lots instead. All modes and caps: Copy settings. A worked example of each: Lot size for copy trading.

Check the first copy

For each action on MT5, this is what to look for:

The copy carries its own reference, so a close on MT5 closes the exact position it opened on TradeLocker, never another trade of yours on the same symbol.

How fast? Measured on our own demo accounts, MetaTrader source to TradeLocker, 13 and 14 October 2026 (32 copies): median 0.48 s from the signal reaching HydraSync to TradeLocker confirming the fill, and 9 copies in 10 under 3.4 s. Most of that time is the broker executing the order.

When a trade does not copy

**Symptom: nothing appears on TradeLocker, and the trade is not on the Signals page.** The signal never left MT5. Check that the terminal is open, Algo Trading is on (green button), the EA is attached to a chart and shown as running in its top-right corner, WebRequest allows https://hydrasyncfx.com, and the key in ConnectionKey is this account's. The account shows connected on the Accounts page when all is right.

**Symptom: the trade is on Signals with 0/1 copied.** HydraSync received it but did not open the copy. The notification says why. The usual reasons:

• Symbol not found: TradeLocker names the instrument differently (XAUUSD against GOLD, or a suffix such as EURUSD.pro). Add a suffix or a rename for the TradeLocker account; see Symbols.
• Refused by a limit: maximum open trades, daily loss, lot cap, trading hours or the news filter on the link or the account.
• No stop loss with a risk lot mode (see above).
• Price moved too far: the price-gap guard, if you turned it on, compared the TradeLocker quote with the MT5 entry and skipped the copy. Widen it on the link if it is too strict.

Symptom: the size is not the one you expected. Look at the lot mode and its preview on the link, the lot caps, and the minimum size TradeLocker accepts for the instrument. Proportional and risk modes use the balance by default; equity can be chosen instead.

Symptom: the connection test on TradeLocker fails. Check the server spelling and the environment (demo or live). If the login works in TradeLocker but the test reports that API access is off, the broker or prop firm has disabled it for your account: only they can turn it on.

Symptom: a close did not happen. You get a close not executed notification. Check the position on TradeLocker and close it by hand if it is still open, then look at the reason in the notification.

After the MT5 terminal was off for a while: trades opened meanwhile are sent when it reconnects. Turn on max signal delay on the link (off by default) to refuse openings that arrive too late, so you do not enter at a much worse price; closes are always applied.

FAQ

Does my computer have to stay on?

Only for the MT5 side, because the EA runs in your terminal. A Windows VPS keeps it on 24/7. TradeLocker runs on our servers. With MetaApi (beta), nothing needs to stay on. More in Do you need a VPS?.

Can I copy one MT5 account to several TradeLocker accounts?

Yes. Create one link per TradeLocker account, each with its own lot mode and limits. Check each prop firm's rules on copying first: Prop firms.

Can I copy TradeLocker to MT5 instead?

Yes. Make the TradeLocker account the source and the MT5 account the destination; the EA then places the copies in your terminal.

Is my TradeLocker password safe?

It is stored encrypted, used only to connect to your broker, and never shown again in the app. If you change it at the broker, update it with the pencil on the account; its links are kept.

Does it work with prop firms that use TradeLocker?

When the firm allows API access and copy trading. Many allow copying between your own accounts; some forbid it or limit it. Read their rules before you start: Prop firms.
