Tough rules but thing you have in mind is achievable, requires a lot of patience. Have tested the same thing when I started my carrier. I was allowed to give one call when my skills were tested and commodities were new to me after migrating from equities. Many a times there was a very thin margin between calls and stop loss. Observation: Even one point can make a big difference many times, be it stop loss missing by one point or target. But for profit no harm in being flexible. (like today you waited for 50 minute for one single point)- my personal opinion.
