IRS indicates overbought condition
Current price is at the top of the bollinger band.
The price needs to test 20-days moving average before it breaks the resistance of 14,000 USD
There will probably be a pull back to around 12,500USD first.
In case of further downward movement, S2 and S3 levels should be watched
If the upward movement continues without enough consolidation, it would be unhealthy and will end with sharp decrease.
