i intend to follow that thread and learn from it - it's nice to see how traders think and make their decisions. and i hope your ZB + CL positions work out as planned!
It really depends on time and sales and the trigger for your stop. If your stop is "if touched" then it would look like that. If not, then you may be stopped out later on. Use stop market orders for Zn. The slippage "usually" isn't bad. Just steer clear of economic releases and the slippage is minimal.
