Hello intraday traders!
I was wondering an idea to find coin pairs to trade. Specifically, a case when there is a green (or red) candles streak (2...n)  one by one on a certain timeframe (M...H).
Since I don't know how to execute this I am asking your help.

Is there any tool or screener you know that allows to select pairs to trade with such conditions?

Share your experience, please

Could someone please give an advice how or where to find a platform/service with market profile available?
Which one do you use (except trading view pro account)?

So the subject.
Is it possible?
Am i have to own the private key in order to make it possible? I consider a transaction via LN from my personal wallet —> exchange wallet as well.

Theoretically...

I sent all my N btc to a friend.

"Imagination, and here a double spending comes"

It turns out that 2*N btc has been sent.

Is it possible to have below zero balance on my btc balance becouse of double spending?
