Overview: Keep Your Data Safe and in Sync

JCloud lets you synchronize your personal JForex4 platform data across multiple trading accounts. By linking all of your trading accounts to a single JCloud User ID (UID), your preferences and customizations are stored securely in the cloud and kept automatically up to date across every linked account.

Data synchronized by JCloud:

With JCloud, you get a consistent trading environment no matter which linked account you're currently using — log in anywhere, and your setup follows you.

Linking Trading Accounts

Linking accounts to the same JCloud UID is what enables synchronization between them.

1. Open Preferences → JCloud and locate the JCloud User ID (UID) assigned to your current trading account.
2. Copy the UID.
3. Sign in to the other trading account you want to link.
4. Paste the same UID into its JCloud settings and apply the changes.

Once two or more trading accounts share the same JCloud UID, JCloud automatically detects the connection and begins synchronizing supported data between them. No further action is needed.

Tip: You can link any number of trading accounts to the same UID. Unlink an account at any time by assigning it a different (or new) UID in the JCloud settings.

Keeping Existing Chart Objects

When you link an account to a different JCloud UID, existing chart drawings and objects may conflict with the ones already stored under that UID. You choose how this is handled:

• Enabled — the Keep the objects in charts option preserves the drawings and objects currently on your charts.
• Disabled — existing chart objects are replaced by the ones synchronized from the newly linked JCloud account.

Decide which option to use before linking, since it determines what happens to your current chart work.

File Versioning

JCloud automatically keeps a version history for every file it stores, so you can restore or review earlier versions whenever you need to.

The Versions column in the JCloud Explorer shows how many saved versions exist for each file.

To view and manage file versions:

1. Open the JCloud Explorer.
2. Enable the Versions panel from the toolbar.
3. Select a file to display its version history.

For any saved version, you can:

• Open the version
• Import the version from an external location
• Export the version to an external location
• Delete the version if it's no longer needed

Version history gives you an extra layer of protection against accidental changes, letting you roll back to an earlier state of your work at any time.

Multiple running instances: if the same trading account is open in several platform instances at once, JCloud saves the workspace from each instance as a separate version. This prevents one instance from silently overwriting workspace changes made in another — instead, both versions are preserved and you can choose between them afterward.

Storage Quota

JCloud provides 50 MB of total storage per UID.

This quota covers every file stored in JCloud plus all of their saved versions — as your version history grows, it counts against the same limit. Once the quota is reached, JCloud displays an error and blocks further saves until space is freed.

To free up space:

• Delete unnecessary file versions.
• Remove obsolete files you no longer need.
• Periodically review your version history and keep only the versions you're likely to need in the future.

Security Warning

Your JCloud User ID (UID) is a unique access key to your synchronized content. Do not share this key with anyone. Anyone who has access to your UID can access and manage the data associated with your JCloud account.
