I also thought it returns -1 when the block target is out of range (limits = 2-20)

<p>I updated the bitcoin node to version to 140200 on top of which one of my applications was running. There wasn't any issue with the flow of the application <code>estimatefee</code> RPC I get -1 for no matter what I give as the number of blocks. Also the alternate fee api <code>estimatesmartfee</code> returns negative values. 
When I execute the same api on a node with version 140100 it gives me a positive result
How do I resolve this ?</p>

# Estimate Fee returning -1

(Asked by: username_0 on 2017-09-01)

I updated the bitcoin node to version to 140200 on top of which one of my applications was running. There wasn't any issue with the flow of the application `estimatefee` RPC I get -1 for no matter what I give as the number of blocks. Also the alternate fee api `estimatesmartfee` returns negative values.
When I execute the same api on a node with version 140100 it gives me a positive result
How do I resolve this ?

-1 means "not enough information for an accurate estimation".

Try with a higher confirmation target.
