When I request an assetlist from a US-based OANDA demo account, I get this line.

Does this look right? Does the trading cost seem a little high?
I'm asking because I am having a terrible time reproducing the equity curves shown in the Workshops, as a starting point. I know that there are many reasons for differences, but the differences are extreme, like -12% instead of +30% AR, for the same asset and time range. In particular, the last year of Workshop 4 does not look like yours. It's much worse.
