So lets say I put in $100 dollars. I buy while its at a low of $10,400. The price goes up to $10,400 and I sell. Whata my profit?
How can you make profit if you do buy and sell into same amount?
Well It seems a loss to me since there is no change in the buying and selling price. You will be paying fees along the way, so you need some gains.
Calculating profit is quite easy. Basing on your example, you can't say you want to calculate profit, but losses instead. Because you bought $100 when the price is $10,400 then you sold your 100 minus transaction fees, when the price is also 10,400.
