Tempted to buy some, but I told myself for the first time to be disciplined and stick to a limit order 10% below ATL.
Perhaps the sign of the bottom reached, is actually myself. Let's see, happy either way.
I think that you are correct by 1) establishing your budget and your target buy points and attempting to stick to your plan and 2) assessing, from time to time, whether you believe that market conditions might justify that you tweak your plan to some reasonable degree. Frequently, there can be a considerable degree of ongoing tension regarding whether tweaking is prudent or just to maintain the original plan. Furthermore, the initial thoughts about tweaking might lead you to a compromise tweak, rather than the more extreme version that initially came to you.
