I have about 90,000 Crypto Currency trades in the last 6 months. The trades involve about 15 Crypto Currency pairs. If the pair is of the form A-B, eg BTC- TUSD, the trading fees are different based on B and whether that particular trade was a Maker trade or a Taker trade.

The data is in MS Excel (trades and non trade transactions) and I need a profit audit of this.

The profit audit involves:
(1) Computing the gross profit, net profit (after fees) for each Currency Pair and tabulated by month
(2) Creating a trail of buy and sell across different Crypto Currencies, beginning in Feb up to Aug.
