I would like to use 'asset structs' for storing such synthetic price series for all the out-of-the-box convenience and seamless interface of the usual 'named' assets: accessing prices, AssetVars, etc..

I added "USD" explicitly to the asset list with "!!!" for Symbols : Zorro complains of no prices in the init run and then ignores such asset.

- I tried to create some dummy t6 files with 1 record per year -> 'not enough ticks', says Zorro, and ignores the asset

- put "!!!EUR/USD" in the Symbols field - > Zorro - for some reason - returns "USD" as SymbolHist -> and ignores such asset (i.e. the last used asset remains 'active')
