Equal-weight portfolio

Estimated total cost of buying and selling, including commissions, the bid-ask spread and slippage. One basis point (bp) is 0.01%; 2 bps is 0.02%, or $20 on a $100,000 position. This combined cost is deducted once per trading day, not once per side. It applies to the intraday strategy, not the buy-and-hold comparison.
