How to tell if proxy is working (First time using proxy)

[Trayarc]

So I purchased some private proxies but was struggling, I think because I live in New Zealand, most private proxy sellers wouldnt take my NZ money,

anyway got 5 private proxys and set them up using proxifier, only to find out they only connect using https not socks5.. Using mirror mode and have set up a rule for my proxies to open different clients with different proxies ( Renaming the jagexlauncher.exe to jagexlauncher1.exe ) 

Using the HTTPS has connected and I've attached a osbot mirrior client to it and proxifier is showing the connection still, the traffic is spiking on the connection but so far its been running for 15 minutes and is still sending and receiving but its not much, only 12.8kb sent and 100kb received... Is this working or not? I wanna run multiple accounts on different ips using mirror mode. TYTY

Use Maxthon Browser, connect to the proxy through the settings and then google check my IP.
