Hey great job including a picture, so i can really see what your thinking, and asking.. So your bases are pretty good.. except you have to listen to what those bases are telling you.. How strong of a bounce happened at the previous base, tells you how interested the buyers are at that price, and how much of a surprise a crack will be.. (big surprise, big panic) and what you want to buy is a panic drop.. heres the same chart.. but the arrows are at bases that are not very strong, so you wont get a big panic and you wont get a good bounce.. 
So I wouldnt draw in the base if the last bounce wasnt strong.. i hope this helps.. and the last bounce is a question mark, because it was a little stronger but still not great, and I just dont see the panic,, we need a real drop.. this is grinding down here and giving small drops and small bounces
Thanks Luc! This is helpful. We'll see how it goes!
