@Colin Crowson Here's the problem: I didn't see the little popup down in the lower left corner (large monitor) that says "data point unavailable". Apparently, my plan, Pro+, is somewhat limited on the backtesting data: "For Pro and Pro+ plan holders, the length of available intraday data is calculated as follows: from now to 6 weeks back multiplied by timeframe(in minutes), i.e. you can go 6 weeks back on the 1-minute chart, 12 weeks back on the 2-minute chart, 30 weeks back on the 5-minute chart, 90 weeks back on the 15-minute chart and so on. The higher timeframe is selected, the more intraday data is available." Maybe it's time to upgrade
