Dimitris, I had to chuckle here. I get the feeling if I were to ask you for directions to the restroom your response would be -
"oh it's easy, just do this....
MaxGraph = 8;K=EMA((H+L+C)/3,10);S1=2*(K-Ref(K,-1))/(K+Ref(K,-1));RS=100+1000*EMA(S1,3);Graph0=RS;Graph0Style=1;Graph0Color=7;Graph1=110;
Your programming skills are amazing. DIMITRIS TSOKAKIS <TSOKAKIS@xxxxxxxxx> wrote:
