Disliked{quote} They are not the same. Lets do an example. For the sake of our example, buying earned positive swap and selling cost negative swap. Secenario #1: 2 lots buy and 1 lot sell = net position of 1 lot buy. You are earning less than 1 lot of swap though due to the imbalance in swap (always to brokers advantage). Scenario #2: 1 lot buy = net position 1 buy. You earn 1 lot of swap. You could literally do this for any amount of lots in either direction. When you have open hedged positions within the same instrument you are paying unnecessary swap...Ignored
The example you gave holds true if both legs are closed at the same time. Not much point to hedging if that is the case,
I am not supporting hedging as a strategy. Just pointing out the simple math of the costs incurred.
