If you don’t provide the currency in the trade/order request then the trade is placed in the currency of the market. If you do provide the currency and it doesn’t match the market’s currency you’ll receive this error. I would suggest leaving the currency out of the request. If you want to place a trade in the other currency (for a given currency pair market), then find the market which has the other currency specified as it’s base and use that market.

Using a different trade currency makes more sense if you’re using markets such as equities and commodities etc.
