I would like to know if my spread (arbitrage) calculation is correct or wrong. as an example i have bitcoins which i would like to use for the ethereum i am going to buy at market A and sell at market B.
1(BUY AMOUNT BTC * BID PRICE = BUY PRICE)
2(BUY AMOUNT BTC - WITHDRAW FEE = SELL AMOUNT BTC)
3(SELL AMOUNT BTC * BID PRICE = SELL PRICE)
4((BUY PRICE - BUY PRICE * TRADE FEE) + WITHDRAW FEE) = TOTAL BUY PRICE
5((SELL PRICE + SELL PRICE * TRADE FEE) - WITHDRAW FEE) = TOTAL SELL PRICE
6(TOTAL SELL PRICE - TOTAL BUY PRICE = TOTAL PROFIT)
What i don't understand from this calculation is why is it BUY PRICE - BUY PRICE ?? and SELL PRICE + SELL PRICE ??
