How much do you invest?

Twenty Grand

Total "how long is a piece of string" question but I'd like to hear how people manage the amount of money they invest.

I've been playing with DeGiro for 6 months and doing alright with 5k. Up about 5% based on advice from here, Motley Fool and general googling.
I want to slowly put in more but I'm unsure how reliable this can be as a savings and investment fund.
Do people here put X% of their salary in each month, maybe a few k once or twice a year, or do you add more when you see a particular trade you want to make?
How confident are you in your returns?

Good work. I'm absolutely no expert, so I'd hesitate to provide any advice, other than that I've read that a spread of index funds over the long term are the safest way to go.

This is something I'm interested in learning about in DeGiro. Can you invest directly in index funds?
