calculate custom number of candles average

[saadatfx]

Hi
I want to calculate this :

v=(highest value of price in previous 9 candle+lowest value of price in previous 9 candle)/2

and I want to open position when the candle closes higher than 'v' vlaue and a moving average at the same time. How can I do that?

Thanks

Highest and lowest can be found in Market properties. You should also check out Williams % range, it does basically that
