Where I can find information about day trading on binance? I cannot find thread on this forum, but I think there has to be also such thread or am I wrong?
Maybe, it's a good idea to check the official Binance website, e.g. here:
A Complete Guide to Cryptocurrency Trading for Beginners (It's quite long, 63m reading time, but it's worth it)
You will find various guides on pretty much every "trading topic". Their guides are quite useful, especially for newcomers. Pretty detailed and easy explained. Just dive in and check them out.
Additionaly, I can only agree with the recommendations of the posters above. Just browse the Bitcointalk trading section. You will find a lot of helpful information there. Good luck!
