Internet backup: a boring investment with high returns

[Shadow Trader]

A scalper relies on a stable connection more than most. A dropped connection during a position is a real risk.

A second connection, such as a mobile hotspot from a different carrier, provides a fallback. Many routers support automatic failover between two sources.

Wired Ethernet is more stable than Wi-Fi and lowers latency slightly. A decent router and a reliable provider matter more than raw speed, since trading data uses little bandwidth.

Testing the backup is vital. Many people discover during an outage that the hotspot data plan is exhausted or the device is not charged.

A small uninterruptible power supply keeps the modem, router and computer running through brief outages.

Recording connection issues in the journal, including time and effect on trades, supports decisions about upgrades.

The total cost may be modest compared with a single bad fill during an outage.

What is the connectivity backup here, and when was it last tested?

My backup is a 4G router with a SIM from a different provider than my home line, plugged into the main router's second WAN port so it switches over by itself. I tested it the honest way about a month ago by pulling the fibre cable in the middle of a demo session. The switch took about twenty seconds, and the platform reconnected a few seconds after that.

The surprise in that test was the UPS. I had assumed it covered everything, but the fibre box was plugged into a different socket, so in a real power cut the backup would have been the only connection working anyway. Worth tracing every cable rather than trusting memory.

The other habit I picked up is keeping the broker's mobile app logged in on my phone using its own data. If both connections die, I can still close a position from the phone. It has saved me exactly once, during a storm, but that one trade more than paid for the whole setup.
