I am currently in the process of writing my first trading strategy. I calculated ratio adjusted data and I am wondering how I can include transaction costs in ratio adjusted data?
The ratio adjustment is calculated as follows:
Ratio adjustment = (Price new contract - Price old contract)/(Price old contract)
Adjusted prices = (all old futures * ratio adjustment) + Prices new contract
Since I use historical data ranging from the 80's to the end of 2014 there are multiple rolls. For every I make these adjustments (iterative process). This formula is lacking transaction costs. How should I account for transaction costs?
