math question

i'm not thinking too good at the moment!

say you have a 5 day simple moving average:

((close1+close2+close3+close4+close5)/5)

i'm looking to determine at what price today's 5sma will be greater than yesterday's.

i'll give an example:

say yesterday a stock had a 5sma of 25.8

((25+27+24+25+28)/5) = 25.8

for today's 5sma to be greater than yesterday, then

((27+24+25+28+x)/5) > 25.8

can someone show the steps to finish this so i can figure out at what price x makes this equation true? it's been a while since i've done this stuff!

thanks

 

X must be greater than the price you have dropped, i.e. greater than 25

 

lol thank you! it seems so obvious now... thanks!

 

Mathematically speaking,



(27+24+25+28+x) /5 > 25.8

(27+24+25+28+x) > (25.8)(5)

104+x > 129

x > (129 - 104)

x > 25
