VT Trader -> MT4 formula - page 2

Hi Everyone, I've been using VT Trader for awhile, but am shifting over to Alpari UK soon. In VT I've been using Chaikin's Money Flow (which someone was kind enough to post on this forum!). However, I noticed that the formulas each platform uses differ a bit. To be quite honest, I like VT's formula better since the CMF has a weakness -- it does not account for price gaps. If a gap in prices occurs, the CMF indicator will have a NULL value (i.e.: no value) for n-periods after the gap. However, the formula has been slightly altered in VT Trader to avoid any NULL values. Here is VT's formula for CMF (note that coding language is not the same as MQL): _AD:= if(((((C-L)-(H-C)) / (H-L)) * V)=NULL,0,(((C-L)-(H-C)) / (H-L)) * V); _CMF:= mov(_AD,periods,S)/mov(V,periods,S); This is VT's formula for Chaikin's Accumulation/Distribution: _AD:= cum((((C-L)-(H-C)) / (H-L)) * V); I have attached the CMF indicator for MT4, and if anyone knows how to translate VT's CMF formula into the MT4 one for me, it would be greatly appreciated!!! If not, well no harm asking. Thanks heaps, Venge.

Here you go

A comparison of VT trader version and this one.

PS: smoothing (moving averages) in this one is with metatrader built in moving averages : simple, exponential, smoothed and weighted. Additional ones need to be added separately)

And to finish it

_________________________

Added : triangular moving average, sine weighted moving average, volume weighted moving average and end point moving average smoothing for stochastic and signal values. So now the complete list of methods is :

0 - simple moving average
1 - exponential moving average

2 - smoothed moving average

3 - linear weighted moving average

4 - triangular moving average

5 - sine weighted moving average

6 - volume weighted moving average

7 - end point moving average

It took some time because of the need to check everything (comparisons showed some rather serious errors on both ends). First the metatrader (an a lot of trading platforms) side. Unfortunately triangular moving average formula that is used as a standard formula (the SMA(SMA(value,MathCeil(halfPeriod)),MathCeil(halfPeriod)) is wrong (it, for example gives same results for periods 11 and 12, and as a matter of fact skips every even period which is not correct) There are 2 ways to calculate it accurately and I choose to make one pass calculation (calculating simple moving averages would make it a 2 pass calculating) Also it seems that the sine weighted moving average that is available on metatrader is wrong. But than that same sine weighted moving average is dead wrong on VT trader (the most similar to sine weighted moving average is triangular moving average but on VT trader it gives results like these (remember - that should be a moving average and not some cycle plotting))
