quite an interesting lot of questions, last one first: of course it's a minus, you said so yourself. Spaces: I guess the less spaces the better, except when it's 'and' or 'or' things like that.

now for the daily vs weekly: an example by way of illustration: if you want to create a formula using say an average of 50 weeks closing price, you'd have to make that: mov(c,250,s) on the daily, but if you want to view it on a weekly chart, you'd need to use 50. I don't think you can have it both ways.

Hi Amory

Thanks for your explanation. I have worked back over the exercise and have a better understanding of what the formulas now mean. No it wasn't part of an exploration; it was an exercise showing how to create an indicator viewed as a histogram. It compares the power of bulls and bears to average consensus of value.

I had no trouble following, creating the indicator and completing the exercise - it was just getting my brain to fully understand it so thought the best way to reinforce was to go over it again. This was the first exercise in the home study course I'm currently doing so I found it a little full on. I'm determined not to give up....I'm hoping things will start to fall into place soooon. Thanks again.
