The protective stop loss order may be placed to realize some profits if cpo futures hit 2167 even though the stop and reverse sell trade signal for the 60-minute indicator Y is still not reach the level yet for 4pm trading session which is given in advance in this blog. It may be just a part of profit to be taken while leave some positions.
Just take note: protective stop and not a "stop and reverse trade", it is just to protect some profit. It is basically you lose nothing except the huge floating profits that gave up due to following a kind of trading system like a set of program.
