Hi I need help with math if I want to know the midprice of a range I do this: {50% range} (High + Low) *0.50 or a 75% {75% range} (High- (High-Low)*0.75) Now, if I want do know the percentage between High and Close I do this: ((High-Close)/100) My problem is the result that this formula give me. Let's see with the S&P friday data. ((1008-988)/100)=0.20 That 0.20 indicates a 2% range but if we look tho the previous formulas the 0.50 and 0.75 indicates a 50% and a 75% respectively. So, that 0.20 could be read like 20% and not 2%, correct? Can anybody help me with this problem? I'm going nuts with this Thank you

Midpoint of the day: (high-low)*.5 + low I'm not sure what you mean by 75% range, so I cannot give you a forumla for it. Percentage between high and close would be either: (high-close)/close (percent difference compared to close) or (high-close)/high (percent difference compared to high)

I'm not exactly sure what you are asking, but try: (High/Close-1)*100 1008/988 = 1.0202429149797570850202429149798 1.0202 - 1 = 0.0202 0.0202 * 100 = 2.02% The high was 2.02% higher than the close.

1008-988/988 = 0.0202 Is that what you want ? That's the % difference between those two numbers. If you want the midpoint: 1008+988 / 2 = 998 If you want the 3rd quartile: 988 + (1008-988 * 0.75) = 1003 I have no idea if that's what you want, but here si what i think is what you want.

Or (if that one is still not complicated enough for you) you could use (-high-low)*.5 + low + high I personally prefer (exp(2*i*pi)*high+ln(e)*low) / sqrt(4) * abs(sin(1.5*pi))
