we need to create some buttons to zoom in/zoom out. Also need to set zooming limitation. Is it possible to do these things?
Yes, this is possible using axis SetMinMax method as in the example Yeray posted here. Using SetMinMax you can set the zoom factor and also limit the maximum and minimum zoom levels.

I am trying to make a program to count the dots on all the dominoes in a picture, like this:
I want it to be a JavaScript function. I have tried to understand how to use tracking js with tutorials, but they're all abput face recognition. I only want it to detect colored dots and output how many of them are present in a picture. Is that possible in any way? Thanks for any help!
Yes you can by using some image recognition such as https://trackingjs.com/ or other.

Is it possible to show a little arrow at a specific price and time, indicating entries and exits in an AMChart? Something like:
If not, is there at least a way of creating custom drawing elements in the chart (circles, lines, squares) similarly to this but using a candlestick chart, not a line chart?
If none of that is possible, does anybody know about a JS library that's capable of doing so?
Thank you!
You can use events for this purpose: http://www.amcharts.com/demos/stock-events/
In the demo it's line chart,but events can be used with candlesticks as well.
