Read it for shape, not slope. Where are the flat periods and how long are they; is the max-drawdown a single event or a pattern; does the strategy make its money in a handful of months; does the slope change after a particular date, which often marks either a regime change or the end of the in-sample period.
A curve that rises smoothly with no meaningful drawdown is a warning rather than a selling point. It usually means negative skewness, an unmodelled cost, or leakage, because real strategies with real risk do not produce straight lines.
Equity-curve trading, turning the system off after N losing days and back on later, is usually a bad idea. It adds parameters, cuts sample, and mathematically cannot help unless the strategy's returns are autocorrelated, which is testable and usually false.
