Quote from niko:
The fact that there was no RET in that move, was what at first led me to treat this down move as a down wave and the next up move as the RET.
But I guess that is not the answer you are looking for.
I have tried to come up with an answer, but it really does not tell me anything different, that there was no entry at the moment to take the short side of the trade.
Now, after thinking about it a little more, the only thing I can come up with is air pocket, but I am not sure.
At the time it occurs, however, you don't know that there will be a "next upmove". You have to trade what's in front of you.
As I said yesterday, when a supply/demand line is broken, the imbalance has shifted from one side to the other. As Gringo said, you then want to watch for signs that will tell you how much it has shifted. If there's no retracement in a downmove after breaking a demand line, then there's no entry, just jumping in because the line has been broken isn't going to work over a series of trades.
Therefore, the first thing you look for after the break is a retracement. If there isn't one, there's no short. However, there are only two outcomes here: that the move will be brief and not worth trading, or that price will collapse and you'll be left with no trade at all. The latter can happen, but if it does, a serious move to the downside isn't going to be short-lived and there will be an opportunity at some point to enter if one just waits for it. Yes, it's possible that price will reverse right after the short is placed, but that's a separate issue.
If there is a retracement and the short is taken, you then start looking for signs that the move is coming to an end, and this is where the swing lows and the extent of the downmove apply. If the swing lows are not breached and/or the downmove is not extensive -- the one on Friday was 25%, as I pointed out in the questions -- then you have to be prepared to exit as soon as the supply line, which you have by now been able to draw, is broken and look for a retracement in the subsequent upmove to go long again.
There's nothing new here, but until the trader puts it in his own words and makes it part of his own plan, it's just PAbabble.
To back up a little, you say in your post to "trace a line" and "look for signs of change". Where would you trace a line here, from Friday's pre-market, and what signs of change would you look for?
