What that means is if it is a sell trend, keep scalping with sell. Do not do any buy. I do not know whether it is going to be accepted by the scalper, but this is what I truly believe. We should never trade against the trend. Experienced traders can share their opinions about it more do not listen to who reffer you to use only the smaller time frames and this is wrong concept i guess open position when the smaller time frames have same direction with the higher time frames
