That is possibly true if one is overtrading or perhaps trading the 1 min chart. However, trading a chart only as big as the 5 min chart allows ample opportunity to post real time calls. ---(One minute can be done as well, it's just a little more challenging to send postings.)
As can be seen, there is no advantage to using the scribble method over any other entry method. The advantage is in the trade management. Scribblers do not talk about this. They instead focus on being right only.
