Graham is correct. You have to use a chart of the shortest timeframe.
If you want to show 5 and 15 minute data you will have to plot it on
a 5 minute chart. You cannot plot 5 minute bars on a 15 minute chart.
I use something like this so I can switch between charts without
having to change the code. The example assumes the longer period is
three times the chart interval. It calculates a MACD and Stoch in a
timeframe 3 times the current chart interval.
// Timeframe calculations
tf = Interval() / 60; // interval is in seconds
tfp = tf * 180; // chart interval * 3 * 60seconds
TimeFrameSet(tfp);
MacdTf = MACD(r1, r2);
tfStoch = StochK( StoPer, Kper);
TimeFrameRestore();
MacdTfe = TimeFrameExpand(MacdTf, tfp);
tfeStoch = TimeFrameExpand(tfStoch, tfp);
plot it as usual but expect to see the 15 minute plot to be flat for
three 5 min bars. The current bar can change but the previous lines
will be flat for three bars for each 15 minute period.
This part of you code doesn't make sense:
> C5=Ref (C,1); this is looking ahead 1 bar. Is that what you want to
do? You can do that but not from the current bar. And your other
calculation is not looking from a previous period. That will give
unexpected results.
> BuyPrice = TimeFrameExpand (C5,in5Minute);
> Buy = C>1.45;
> Sell=C>50;
You got the 15 min BuyPrice but don't use it in the next 2 lines. Do
you want the 5 minute C to be > BuyPrice + 1.45?
A buy of C>1.45 does not make sense compared to a sell of C>50. You
will have a buy on all bars C>1.45 and then a sell on all bars with
C>50. A cross function makes more sense but since I can't see the
rest of your code all this may be fine.
