Yep, exactly!
At least, that is how it worked in the DualMomentum code I played around with.
I don't know if you actually want to hard code "BTCUSD" string or similar though... Code might be more powerful if you access the different assets by using "Assets[i]". Then you can switch out the asset list and test the system on different ones without changing any lines in the code. Like, if tomorrow you decide to trade a different crypto than BTC for example.
