What do you all use to calculate your estimated balance and gain/loss? There's the cryptsy estimation, CAT estimation, total cumulative gain, and market cumulative gain. I have no idea what is the most accurate.
Been saying for a while that we need an exact, per-market, in-play balance, which is the sum of these :
- A. BTC balance held for existing Ping/Pong orders
- B. Coin balance held for existing Ping/Pong orders
- C. BTC used in active Buy orders
- D. Coins used in active Sell orders
B&D need to be calculated in BTC - value at
best current sell price of coins.
The sum of these 4 values is the accurate amount of BTC exposure you have to any one market, and takes into account all coins held in orders regardless of whatever price you hope to sell them for ! This would be the best way to keep track of ACTUAL profit/loss in each market as you just keep track of this total value over time. The gains sheet, whilst useful at showing you profits on
successful Ping-Pongs, is only half the story. As well as these successful trades, you will also have a number of balances held in orders too high or too low outside of the trading area (careful use of limits avoids these risks). These orders may never even get executed.
You also need to add each market coin balance that is NOT in play.
You also need to add the part of your BTC balance that is NOT in play. (Ever gone to make a new Ping Buy order and thought - I wonder how much of my BTC balance is actually available for new trades? Well this is where calculating this value would also come in useful. The same for coin balance above).
The sum of all these values is your actual total current portfolio value.
Note some of these per market values are already calculated on the market Statistic tab, but not all of them.
