Multiple timeframes and max number of bars

October 24th, 2016, 03:35 AM

I use 1-minute interval as data1, 1 day interval as data2. Same instrument (USD.JPY in this case)

I need to access 2,000 bars back for code involving the 1 minute interval. I the 1 day interval to analyze the last 15 bar.

I get the error "Not enough series length" when I specify 2,000 as "maximum number of bars study will reference", unless I load 2,000 days of data. This is even for a trivial strategy that includes only the following code:

print ("d1",close of data1);
print ("d2",close of data2);

I don't need 2,000 days of data before the backtest period starts, is there a way to specify different "bars back" for the different intervals?

TraderWalrus,

not that I am aware off, I am afraid MC requires the max bars back setting for all dataseries.
You could try to work around that by computing your higher timeframe out of the lower timeframe and not load a Data2 or by making the second dataseries available from a different chart using external DLLs.

As an alternative to using the daily data as data2, you can eliminate data2 and build an array from your 1 minute bars using the closed(x), opend(x), highd(x), lowd(x), etc functions. This will eliminate the need to load 2000 days back of bars and also saves the need to have Data2 in your data feed.

I can do something like:

array:

ClosedDay[100](0),
OpenDay[100](0);

if currentsession(1) <> current session(1)[1] then begin

for x = 100 downto 2
ClosedDay[x] = ClosedDay[x-1]
OpenDay[x] = ClosedDay[x-1]
end;

ClosedDay[1] = closed(1)
OpenDay[1] = opend(1)

Now all of the daily data is contained in the array 100 days back, or 15 in your case. Easy Language has a battery of array functions that allow you to perform many of the common functions on arrays such as:

MvgAvg = AveragrArray(ClosedDay, 30);
