Usually gap down means immediate rebound at open (
viewtopic.php?f=2&t=2890&p=254559#p254559) so need wait first. The question here is since usually it rebounds first why not simply buy the open? I don't know, don't ask me.
The first touch of EMA20 usually can tell us whether the market wants to go up or down (
viewtopic.php?f=2&t=2890&p=254580#p254580), so again, wait. It's an ideal place to initiate a short simply because the stop loss would be close, but there's a but, which I explained here (
viewtopic.php?f=2&t=2890&p=254584#p254584), which also explained why it might be too late to short if you waited until the trend became clearer.
Day low indeed was the target (
viewtopic.php?f=2&t=2890&p=254590#p254590).
I think I did very good explanation on why short is always hard (
viewtopic.php?f=2&t=2890&p=254598#p254598). It's a tough decision here. The main problem on short is the rebound always looks sharp which is hard to tell whether it's just a rebound or the low was in.
The final chart is to let you know if you decided to hold what would happen thereafter. So in short, there's only one place to short on the day but unfortunately at that time it didn't at all look like a short.
