Wi-Fi works until the one moment it does not

Wireless connections are convenient and usually fine. They are also subject to interference from neighbours, microwaves, and other devices, and the problems tend to appear in short bursts.

For ordinary browsing, a half-second hiccup goes unnoticed. For a trader with a position open, it can mean a missed exit or a delayed fill.

A wired connection removes one large variable. It costs almost nothing, usually a cable, and makes latency more consistent.

Other points matter too: the quality of the router, the load from other devices on the network, and the ISP's routing to the broker. Sometimes switching providers or using a mobile hotspot as a backup solves a lot.

It is worth keeping a backup route for connectivity, like a phone ready to tether, because outages seem to happen during exactly the moments that matter most.

A quick check: run a continuous ping over Wi-Fi for ten minutes during the evening, then switch to a cable and repeat. The difference in the tail of the distribution tends to be convincing.

What is the backup plan if the main connection drops with a trade open?

A quick check: run a continuous ping over Wi-Fi for ten minutes during the evening, then switch to a cable and repeat.

Short bursts of interference are what make Wi-Fi treacherous: the average ping looks fine and the bad seconds arrive at random. A cable for the trading machine and Wi-Fi only as a backup is the simplest fix.

My backup plan only became a real plan after a power cut in my building took out the router while I had a GBPJPY short open in the New York afternoon. The phone was in my pocket the whole time, but I had never actually tethered the trading laptop to it, so I spent four minutes hunting for the hotspot password and then waiting for the platform to reconnect. The trade was fine in the end, but I didn't enjoy those four minutes at all.

Now the phone hotspot is saved on the laptop and I test it every couple of weeks by pulling the cable mid session and timing how long MT4 takes to come back. On my setup it's usually under fifteen seconds. I also keep the broker's mobile app logged in, so if the laptop itself freezes I can still close everything from the phone.

The other habit is that every trade has a hard stop and target on the server before I let go of the mouse. If the connection drops, the worst case is already defined.
