Return from position resize seems wrong

[bonomat]

Start Situation:

• 100 long
• Average entry price $100,000
• Leverage 2
• Margin: 50,000 sats

Price increases to $110,000

• go 50 short (resulting in being 50 long)
• At the price of $110,000
• Leverage 2

Should behavior:

• We are selling 50 contracts at the price of $110,000
• The value of this would be = 50/(110,000 * 2) = 22,727 sats
• Fee should be 136 sats
• The average entry price should remain: $100,000
• The remaining margin in the position should be
  • = initial_margin - returning_margin - fee
  • = 50,000 - 22,727 - 136
  • = 27,137

Is behavior

• We are returning 27,137 into the wallet and have 27,273 left
