If you place orders through a broker API, you have already run into this. You paste an IP into the whitelist box on your developer profile, everything works, and then you move your laptop to the office or switch to a mobile hotspot and every order starts getting rejected. Most brokers only let you change that whitelisted IP once a week, so a mistake costs you seven days.
The problem is that home broadband gives you a dynamic IP. It changes on reconnect, on router reboot, and obviously the moment you switch networks.
There are two fixes.
\*\*Option 1: ask your ISP for a static IP\*\*
Call Jio, Airtel, ACT or whoever you use and ask for a static IP on your connection. Some will give it, usually on a business plan. It works and it is the simplest option.
The catch is that it pins you to one physical connection. Your laptop is now a desktop. Move it, or fall back to a hotspot during an outage, and you are locked out until the weekly whitelist reset.
\*\*Option 2: route your orders through a cheap VM (this is the one I use)\*\*
Instead of whitelisting your own connection, you put a small virtual machine in the middle. Your orders go from your machine, through the VM, to the broker. The broker only ever sees the VM's public IP, so it does not matter what network you are on. Home Wi-Fi, office, hotspot, a train, all the same.
Oracle Cloud's Always Free tier gives you a machine that costs nothing and does not expire. Other providers work identically.
\*\*Setting it up\*\*
1. Sign up at Oracle Cloud free tier. You will pay a small verification charge (about ₹1) that gets refunded.
2. Pick your home region carefully at signup. This cannot be changed later. Pick India South (Hyderabad) or India West (Mumbai), whichever you are offered.
3. Create a Virtual Cloud Network using the VCN Wizard. Name it, next, create. That is the whole step.
4. Create an instance. Change the image to Ubuntu, and confirm the shape shows the "Always Free Eligible" badge. Download the SSH private key when it offers it and do not lose it.
5. Wait for the state to go from provisioning to running, then copy the public IP.
Five minutes, no coding.
\*\*Actually routing traffic through it\*\*
This is the part that is independent of whatever software you use. Three ways, easiest first:
\*Run your bot on the VM itself.\* If you have a headless Python script, just SCP it over and run it there under systemd or tmux. Traffic already originates from the VM's IP. Nothing else to configure.
\*SSH dynamic port forward.\* Keep the bot on your laptop and tunnel its outbound calls:
ssh -i yourkey.key -D 1080 -N ubuntu@YOUR\_VM\_IP
Then point your client at a SOCKS5 proxy on 127.0.0.1:1080. In Python, most broker SDKs use requests underneath, so this works:
proxies = {"http": "socks5h://127.0.0.1:1080", "https": "socks5h://127.0.0.1:1080"}
Check your SDK actually passes proxies through. Websocket connections often need configuring separately from REST calls. Wrap the ssh command in autossh so it reconnects if the tunnel drops mid-session.
\*WireGuard.\* Full tunnel, more robust than SSH forwarding, more setup. Worth it if you are doing this long term.
Then paste the VM's public IP into your broker's whitelist box and update.
\*\*Verify before you trust it\*\*
From inside your bot's actual network path, hit an IP echo service and confirm the address matches what you whitelisted. Do not assume. If you accidentally put the VM in a private subnet behind a NAT gateway, the egress IP is different from the one shown in the console, and you will not find out until an order fails.
\*\*Two things that will bite you later\*\*
Oracle assigns new instances an \*ephemeral\* public IP. It survives reboots and stop/start, but it is released if you terminate the instance or detach the VNIC. Given the once-a-week whitelist limit, convert it to a Reserved Public IP in the console. Free tier includes two at no cost, and it takes about a minute.
Oracle also reclaims idle Always Free compute. Their published threshold is 95th percentile CPU under 20% over a 7 day window. A VM that only routes a handful of orders sits far below that, so this affects algo traders more than almost anyone. Upgrading the account to Pay As You Go exempts you from reclamation while keeping the Always Free resources free.
\*\*Also worth knowing\*\*
Most brokers let you whitelist two IPs. Register your home connection and the VM, and you have a fallback either way.
This is not Oracle-specific. AWS, Azure, GCP, Hetzner, a ₹300 Indian VPS, all identical. Oracle is just the one that is free indefinitely.

Full disclosure: I build and sell a trading terminal called Imperium, and I made a video walking through this whole setup because I kept answering the same question. In the video the VM connects through the app's built-in router, so there is no SSH or proxy config to do by hand. If you are not using it, everything above still applies, you just wire up the tunnel yourself.

Happy to answer questions.
