Don't want to pollute the OP's thread, but I don't understand this trade. Is this a theoretical exercise, if real money It appears you have net loss after commissions.
NP. From the point of accumulation to the end plots, considering the blue line (HST) is Long and the white Line HST is Short when looking at the terminus of the plots it looks like a net gain as the Long gained more than short lost (considering both legs had same dollar amount attributed to them or "dollar neutral). Good to have the blue superior or more elevated than the white on the chart at the end of the day.
Let's say there was $ 13, 500 in play. A 2% gain is $ 265. Annualized to take into consideration for time in the trade (approximately 5 days, because shares were accumulated into the trade by legging in), the return is close to 146%.
270/13,500 = 2%
365/5 = 73
2% x 73 = 146%
Does not matter if real dollars were used or a paper trade, the math is the same.
