Day trading through a wi-fi connection at home?

Right. My computers all operate via a wifi connection to the internet router in another room. The system has been installed for a couple of months, connected all night, haven't seen any disconnection or data problem as yet.

I don't have a problem with wifi security. The bigger problem would be someone hacking into the bank or the broker. Not very likely, but we all need a bank and/or a broker, so we just accept that risk.

If you really think someone is sitting withing 500 meters of your house with Wireshark sniffing your packets, assuming they have broken through your WPA2 security on the network, yer more paranoid than I would give you credit for. STOP THE MADNESS!

If you know what I know, you wouldn't think I am paranoid. But that's ok, you will learn one day.
 
Where are you getting your data from, and at what speed? Who is your broker? Also, what is your main data line into the router? (Cable, FIOS, other)

I think it'll be fine, unless you're paying bucks for 1ms tick data. IB basic data packs run at 4 VWAP ticks/sec, or a 250ms tick time... and it's bursty too.

You should be ok with a good wifi router. Don't pinch pennies: buy a good one.

My concern would be difficulty in upgrading down the road. if you want to buy a faster and more accurate data feed; say, 1 tick/ms, wifi _might_ struggle a bit with this, but I'm not sure. You could pretty easily test it now with a little Python script to write tick data to a socket at this speed, simulate the flow, and measure the latency.

Finally, if you're gaming, forget about it... you'll get clapped. True gamers never use wireless.

Hello, guys,

I'm relocating to a new apartment and have a few alternatives, but it seems difficult to get a physical cable connection between the router and my office in the alternatives I have at hand.

In my old flat I had the router just beside my computer, so have been using cable pretty much always.

So, how good is a wi-fi connection in 2020?

I mostly day trade manually. No low latency stuff, but obviously a good and stable connection is a must.

If wi-fi is a no-no, I might simply have to find somewhere else to live. :)

Thanks in advance!

You should test not only speed but also the quality of the connection (packets loss).

Test for free, no software installed:

I have fibre cable :
Download speed : 180Mb/s
Upload speed: 20Mb/s
and these are my results:
latency depends of course from where you go to. Distance has huge impact on it.
