RSI divergence?

I am considering a possible retracement in NAS100USD. In addition we are pretty close to the overbuying zone and I don't know if the volume is enough for this growth... On the other hand the USA situation is one of the worst in serveral years and the Trump administration is not the best support for the tech companies...

I don't know and I don't understand why is NAS100 so high but I am thinking it should decrease sooner or later.

What do you think about it? If you have any information about it, I would be very happy to listen to you, please comment here, I don't care if you tell tome I am wrong I am ready to improve!
