In exchanges like Poloniex and Bitfinex when you trade on margin, is the total loan interest fees incurred the same if you close out your margin position within 2 minutes vs 2 days? I ask this because the "loans" are typically on a 2 days contract. Ideally it should be prorated but I am not sure if it's done that way.
Not sure how it works withi Poloniex or Bitfinex but when I do margin trading on Fidelity, margin interest is accrued every day. I am pretty sure that if I buy and sell within one day, it still charges one day's worth of interest... Two days would be more either way though.
Might be different with Poloniex or Bitfinex.
