One important aspect of backtesting is considering the transaction costs for more realistic results. These costs, such as commissions, funding fees, spreads, and slippage, can have an impact on profits. The position details tab in the manual backtester provides access to these transaction costs.

To find information on transaction costs at exchanges, you can check the following links for Binance and OKX (Taker fees are for market orders, and those are the fees you should be looking at):

• You can find the trading fees for Binance here.
• You can find the trading fees for OKX here.

The Realized PnL Breakdown section lets you easily explore:

• Gross PnL
• Open and close commissions
• Funding fees
• The Net PnL

It offers a comprehensive breakdown, specifically designed to offer a clear understanding of your trading performance. The commission and funding fees data are collected every 8 hours only when the position is opened and closed. So when you see a figure like (30*0.02), it means the position was held for a total of 240 hours (30 times * 8 hours). This level of transparency allows you to understand the impact of these factors on your overall results.

The slippage breakdown section invaluable insights into the slippage experienced during your trading positions. Slippage refers to the variance between the anticipated trade price and the actual executed price. Here’s what you can expect from the slippage breakdown feature:

1. The slippage breakdown provides detailed information – Including the expected price, average execution price, and the slippage itself. It is calculated as the difference between the expected price and the actual price incurred during the trade.
2. The slippage section is specifically dedicated to analyzing slippage and does not include other factors like spreads and commissions. It allows you to assess the impact of slippage on your trades.
