hey marcin..... i've never used ms 8 so not sure of it's, if any, limitations as compared to v9..... 4 hour charts were possible with 9 but never worth my time spent..... to create a different time frame you can use excel to find the open , high, low, close of any combined ' lower time frames ' data ..... roughly put, take 3 one hour bars and calculate the open, high, low and close of those to create a 3 hour chart.... it was just too much work for me......
then came v10 which creates instantly virtually any time frame at the click of a button..... it's the way to go if it fits someones budget......
to change the macd parameters you'll need to create a custom macd formula that has inputs.... similar to what preston did here for the tema dema......h
