a few might remember the logic problem involving 12 pingpong balls where only 1 was an odd weight.... in 3 tries with only simple balance scale the goal was to identify the 1 odd weight and say if it was heavier or lighter.... the solution involves doing 1 action that effectively provides multiple insights.... henry has a subtle habit of that same type logic.... have you noticed that at times he uses red or green for formula names.... that 1 action effectively provides multiple insights.... obviously first it provides a name but also second at a quick glance we can focus in on that specific line of code for up or down component of the graph.... ghost today had a question involving histograms.... just below here would have been my answer .... my method , which is seen in anything i've posted, would have been to use 'a' , 'aa', 'aaa' and so on such as, a:=((c+2*std(c,20) - mov(c,20,s)) / (4*std(c,20)))*4 - 2; aa:=if(a>=ref(a,-1),a,0); aaa:=if(a<ref(a,-1),a,0); 2;0;-2;aa;aaa; at first there was an error in my 'to be' green line..... to be honest i had to look several times to decipher which code was for the 'to be' green line.... even though i had just seconds before written it.... just imagine the difficulty had the code been 20 lines long and something written last week....... now here is henry's code presented today.... the use of red/green is,,,, well, even a hayseed can see the vast improvement and he is rewriting formulas at this moment......
