How can I use (Open + Close)/2 or "MidBody()" as the price input?

[rottentrade]

It seems like the price input is limited to reserved terms like close, open, high, low, hl2, hlc3, ohlc4, etc.

But it doesn't allow (Open + Close)/2 or MidBody()...or something like (Open+High+Low)/3.

Is there a way to assign price input to something other than the default.

You can make your own input for choices. Here is an input pricex which lists multiple price choices. A switch statement then include all of those choices (mandatory). You can add more if you want.

You can use price in your code based upon the choice made. Please note that parameters such as those with math symbols must be in quotes.

input pricex = {default close, open, high, low, hl2, ohlc4, "open+close/2", "open+high+low/3"};

def price;
switch (pricex) {
case close:
    price = close;
case open:
    price = open;
case high:
    price = high;
case low:
    price = low;
case hl2:
    price = hl2;
case ohlc4:
    price = ohlc4;
case "open+close/2":
    price = (open + close) / 2;
case "open+high+low/3":
    price = (open + high + low) / 3;
}
AddLabel(1, price);

Excellent! Exactly what I want. Thank you.

One more question please. I want to use a different price input for 2 different indicators, for example, "close" for MovingAverage1 and "o+H+L/2" for MovingAverage2. Can I combine two price inputs into one switch statement or do I need create two switch statements like below? Is there a way to combine the two?

input pricema1 = {default close, open, high, low, hl2, ohlc4, "open+close/2", "open+high+low/3"};
input pricema2 = {default close, open, high, low, hl2, ohlc4, "open+close/2", "open+high+low/3"};

def price1;
switch (pricema1) {
case close:
    price1 = close;
case open:
    price1 = open;
case high:
    price1 = high;
case low:
    price1 = low;
case hl2:
    price1 = hl2;
case ohlc4:
    price1 = ohlc4;
case "open+close/2":
    price1 = (open + close) / 2;
case "open+high+low/3":
    price1 = (open + high + low) / 3;
}

def price2;
switch (pricema2) {
case close:
    price2 = close;
case open:
    price2 = open;
case high:
    price2 = high;
case low:
    price2 = low;
case hl2:
    price2 = hl2;
case ohlc4:
    price2 = ohlc4;
case "open+close/2":
    price2 = (open + close) / 2;
case "open+high+low/3":
    price2 = (open + high + low) / 3;
}


plot ma1 = ExpAverage( price1, 10 );
plot ma2 = ExpAverage( price2, 20 );

I would just use one and use the hybrid price1 from it for the first ema. Then just use close as part of the ema price2.

Another way to do this now that I see how you plan to use this is to make a default template that is part of any chart where you are using different price types. It would be something like this.

def o = open;
def c = close;
def h = high;
def l = low;
def oc2 = (o+c)/2;
def ohl3 = (o+h+l)/3;
etc etc

Or use what you have, but that will be rather cumbersome.

Thanks for the reply. My code has become really bloated lately and it seems to be a drag on the memory. So I would like get rid of any redundant codes.

With that said, I'm constantly testing different parameters, so I think it's more efficient to just create different price inputs. That way, I can just modify those parameters inside the Edit Strategy window.
