Hello,

I try to make a watcher where one field ("spot") from one indice ("mktdata-2020.01.28") will be compared from two fields ("lbound" and "ubound") from another indice ("price-request-2020.01.28") but i am stuck since a couple of hours on the script and this "index\_out\_of\_bounds\_exception" java error.

I gave some ES snippets if someone can help:  
First:

It' s a size problem, when setting Size:10 it worked and i go to a cast error after but when you change the equality in inequality it worked definitly.  
Final solution:
