How to get same symbol from 2 providers

[pmaglio]

If I want to have same symbol being loaded from 2 different providers ( tick data from zenfire and daily data from yahoo ) i have to create 2 different instruments or just one instrument with corresponding symbol map ?

Example : 10 year bonds ( ZN for zenfire and ^TNX fro yahoo). Just need to put its mapping to the existing symbol or add a new one for yahoo ?

This is not the same symbol as far as I know. The ZN for zen-Fire is the 10 Year's Teasury futures instrument and the ^TNX is an option.
