Hi Mladen,

I want to do some similarity analysis in forex data.

I mean , I want to find  out the most corrrelated 1 hourly bar ( same or most similar value in OHLC) bar to LAST  1 hourly bar(OHLC)   in 20.000 bar(OHLC) history .

Is Pearson correlation coef.  enough  to find out  the similarity  of last bar value in 20.000 bar history?Is this possible to do this analysis in metatradervith a script(or EA) ?Thanks.

 

 

dear mlade:

i make my first MTF indicator

but color is black

how to fix it? 

thank's very much

Set the #property indicator_color1 to desired color (it is set to Black now)

Mladen,

Any comment on that?

Mladen,

Any comment on that? 

You can do that with Pearson and simply find the bar with the maximal value of Pearson - you can do that for any time frame and any number of bars since Pearson is not CPU heavy. Best to do that from an indicator though (in order to avoid some array operations)

mr mladen:

i do it but only have one color

i need two color for bull &bear market

Then you have to code it differently (you have to use two buffers not just one for two color histogram)

is it correct sir?
