Backtesting data competition

 
I run my real account on ICMarkets.
I tried backtesting data from ICMarkets and dukascopy (imported from TDS).
ICMarkets data is 100% quality since Jan 1st, 2022.
Dukascopy data is good quality for 19 years.
So, which data will you perfer?

one year back test is not enough, 19 years back test is pretty good, but if you don't know how to use it ( how to make back test ) even 30 years quality data not help. Regards Greg
 
I agree, one year is not enough.
