The most attractive buying opportunities occur at 2 and 4: Buying at around 10,400k with a stop loss a bit below 10k (2) and buying at the retest of the regression line with a stop loss a bit below the regression line (4). However, since there is no guarantee that a bull run similar to the one that occurred at the end of December will play out, buying at 2 is riskier. If price does bounce at around 10,400k and stall shortly above the regression line, then purchasing at the retest of the regression line would be the more attractive option for cautious traders, as the outlined bull scenario will have been given more time to prove itself. The drawback, of course, is that you miss out on a larger portion of the run.
This is my perspective on what I see as potentially happening over the course of the next few days. Price action may not play out as it did during the brief bull run that started at the end of last year, or even if it does, some event may hinder this scenario from playing out fully. is important. contracts expires on the 26 of January, for instance.
Note: I used an tool to sketch out the bull scenario, but I did this only to highlight price action in a way that presents the information clearly - both visually and in writing. I didn't count waves or make sure that wave counts follow conventional rules, this is not an analysis of price action.
