*Hi,

I found in my archive the Trading System: 3-Bar System by Larry Williams, but it's for ProRealtime, if someone could turn it into EasyLanguage, so you could test it in the various Markets.

Thank you in advance.

Explanation: Total Price is the average value between open, high, low and close: (O+H+L+C)/4

// 3-Bar System long (simple)
*
mal=Average[3](low)
mah=Average[3](high)
*
trnd=LinearRegressionSlope[3](TotalPrice)
*
c1=(trnd[1]>0)
c2=(trnd[1]<0)
*
IF NOT LongOnMarket AND c1 THEN
BUY 1 CONTRACTS AT mal[1] limit
ENDIF
*
If LongOnMarket and c2 THEN
SELL AT mah[1] limit
ENDIF

// 3-Bar System short simple
*
mal=Average[3](low)
mah=Average[3](high)
*
trnd=LinearRegressionSlope[3](TotalPrice)
*
c1=(trnd[1]>0)
c2=(trnd[1]<0)
*
IF NOT ShortOnMarket AND c2 THEN
Sellshort 1 CONTRACTS AT mah[1] limit
ENDIF
*
If ShortOnMarket and c1 THEN
EXITSHORT AT mal[1] limit

ENDIF

-------------------------
However, the author suggests the following values based on the tests carried out:

mal=Average[17](low)
mah=Average[17](high)

trnd=LinearRegressionSlope[12](TotalPrice)

If it'll help anyone, the T.S. has been turned into Easylanguage here:

https://www.elitetrader.com/et/threads/3-bar-system-by-larry-williams-from-prorealtime-to-easylanguage.342399/

Maybe this can be an EasyLanguage version:
(No debugging done)

//Moving averages:
Var: mal(0), mah(0);
mal = Average(Low,3);
mah = Average(High,3);

//Trend analyzer:
Var: trnd(0), TotalPrice(0);
TotalPrice = (O+H+L+C)/4;
Trnd = LinearRegSlope(TotalPrice, 3);

//Uptrend VS Downtrend
Var: c1(0),c2(0);
c1=(Trnd[1]>0);
c2=(Ttrnd[1]<0);

// 3-Bar System long orders
If Marketposition<=0 and c1 then
BUY 1 contract at mal[1] limit;
If Marketposition=1 and c2 then
SELL next bar at mah[1] limit;

// 3-Bar System short orders
If Marketposition>=0 and c2 then
SELLSHORT 1 contract at mah[1] limit;
If Marketposition=-1 and c1 then
BuyToCover next bar at mal[1] limit;

However, the author suggests the following values based on the tests carried out:

Then use these instead:
mal = Average(Low,17);
mah = Average(High,17);

trnd=LinearRegressionSlope[12](TotalPrice)
Then use this instead:
Trnd = LinearRegSlope(TotalPrice, 12);
}

All of you...
