How can I copy trades between my machines over the same local network?

Replikanto has a feature that allows it to receive trades from another Replikanto via the local network (the same WiFi, for example). In this case, you can send trades from a Replikanto running on machine A to another Replikanto running on machine B within your home or office with no extra cost, although all Replikantos must have valid licenses.

What is Local Network Copying?

Local Network Mode (also called Network Mode) allows you to copy trades between Replikanto instances on the same local network without using internet-based Remote Copy. This is ideal for:

• Copies within the same home or office on the same WiFi/network
• Situations where you want to avoid internet latency
• Multiple trading computers in the same physical location
• Testing configurations before deploying to remote locations

Prerequisites

Before setting up local network copying, ensure:

• Valid licenses: Both Replikanto instances (leader and follower) must have valid licenses
• Network connectivity: Both machines must be on the same local network (same WiFi/router)
• Firewall configured: Windows Firewall on the follower machine must allow inbound connections (see firewall configuration guide)
• Same instruments: Both Replikanto instances must have the same instruments available

Finding Your Follower's IP Address

To connect from the leader to the follower, you need the follower machine's IP address on the local network:

1. On the follower machine, open Command Prompt (Windows)
2. Type ipconfig and press Enter
3. Look for "IPv4 Address" under your network adapter (usually 192.168.x.x or 10.x.x.x)
4. Use this IP address when registering the node on the leader machine

Step 1: Configure the Follower (Receiving Machine)

On the machine that will receive trades (the follower), configure Replikanto as a network follower:

Important steps:

1. In Replikanto, enable Network Follower mode
2. Select the Network Adapter that connects to your local network (see Network Adapter configuration if you need help)
3. Note the IP address and Port displayed (default port is 4547)
4. Don't forget to select the follower accounts that will be copying the leader's trades
5. Click Enable or Apply to activate network follower mode

The follower is now ready to receive trades from the network.

Step 2: Configure the Leader (Sending Machine)

On the machine that will send trades (the leader), register the follower as a node:

Important steps:

1. In Replikanto, locate the Node List (bottom left of the window)
2. Click to add a new node and enter the follower's IP address and Port (from Step 1)
3. Click the circle next to the node to enable sending trades to that remote follower
4. Ensure the leader account you want to copy from is properly configured

The leader is now configured to send trades to the follower.

Step 3: Test the Connection

Verify that local network copying is working:

1. On the leader machine, select an instrument in both leader and follower accounts
2. Place a test trade (limit order works best for testing) on the leader account
3. Check that the trade appears on the follower account
4. If the trade copies successfully, your setup is complete!

Troubleshooting

Trades Not Copying

If trades aren't copying from leader to follower:

1. Verify network connectivity: Can you ping the follower machine from the leader?
2. Check firewall: Ensure Windows Firewall on the follower allows inbound connections on port 4547 (see firewall troubleshooting)
3. Verify IP and port: Ensure you entered the correct IP address and port (default: 4547)
4. Check network adapter: Ensure you selected the correct network adapter on both machines
5. Verify accounts are selected: Ensure follower accounts are properly selected in the configuration
6. Check for Http Listener errors: See Http Listener troubleshooting

Firewall Blocking Connection

If you suspect the firewall is blocking the connection:

• Temporarily disable Windows Firewall on the follower and test if trades copy
• If they copy with firewall disabled, follow the firewall configuration guide to add proper rules
• Check for third-party firewall software (Norton, McAfee) that may also need configuration

IP Address Changes

If your follower machine's IP address changes (can happen with DHCP):

• Update the node registration on the leader with the new IP address
• Consider setting a static IP address for the follower machine in your router settings
