 # Halfway between the 9 and 21 EMA

I'm looking to create a label that indicates what the price is that is halfway between the 9 and 21 EMA's. Maybe something like current 21EMA + 9EMA /2. I just don't know how to create the label. Of course I can eyeball it using the cross hairs etc but I thought if I could create a label it'd be a lot faster. thanks!

That would be a very easy code introduction to Thinkscript and I'm sure you could do it if you took the time to learn... You already know the logic so just implement it... Better to learn than to rely on us for such simple bits of code...

I understand that the Add label function is what ultimately results in the label but i cant figure out how to take the next step where you can put a formula in. I want to learn, but I have a hard time finding the resources to do so expeditiously without being lead around in circles. If you can help me I'd sure appreciate it.

I'm Just learning too. I used to TOS EMA code and went from there. Try looking at all the indicator codes and you can start understanding them.

Code:
``````input EMA = 21;
input EMA2 = 9;
input price = close;
input displace = 0;

def AvgExp = ExpAverage(price[-displace], EMA);
def AvgExp2 = ExpAverage(price[-displace], EMA2);
def Diff = (AvgExp + AvgExp2)*.5 ;
