Indicator visible or indicator appear

[Laudable222]

I have three questions please.

1. please, in which situation do you use indicator appear and in which situation do you use indicator visible, for custom indicators.
2. do the parameters of an indicator matter that much. i was able to upload my mt5 indicator, but it got the buffers and no parameters, will it still work?
3. how effective is using a second window indicator to create an EA using FXdreema. the indicator shows colored boxes for every candle.

1. That depends on your strategy and the available buffers. What do you need?
2. No, you need both of them I recommend you to read these tutorials to help you get the parameters:

3. Do you mean a subwindow or a new chart?
