In years of using TS4 and TS2ki, I always found multi-data charts
to be the most frustrating mess in the whole product. Things
often didn't work the way you thought they should. When you had
to use them they were lifesavers, but if you didn't have to use
them it was better to avoid them.
Without spending some time digging into exactly what you did, I
don't know exactly what's going wrong. But I can show you how to
do it without multiple data streams.
In your case, assuming the 34-bar EMA is all you need from your
13min chart, it's fairly easy to do that without a 13-min data2.
Just calculate the EMA in your EL code using your 1min bars.
For example let's say you were using xaverage(Close of data2, 34)
like you said. To calculate that based on your 1min chart, you'd
do something like this:
(untested, since I don't have my TS here, but should be close)
inputs: EMAlen(34);
vars: alpha(2/(1+EMAlen)), EMA(Close);
if mod(BarNumber, 13) = 0 then
EMA = alpha * Close + (1-alpha) * EMA;
alpha gets initialized to the proper value for an EMAlen-length
xaverage. EMA gets initialized to the value of Close on the
first bar, to give it a reasonable starting value.
Then every 13 bars, you just calculate the new EMA value using
the close of that 1min bar.
This may not exactly match the EMA on a 13min chart, because it
may be offset a bit. E.g. the 13min chart might have bars ending
at 10:00, 10:13, 10:26, etc, while this code might be
recalculating on the bars ending at 10:03, 10:16, 10:29, etc.
But the results should be close enough for your purposes.
