Hi All Does anyone have any good previous days high/low breakout for an hourly chart? Or some links? Many Thanks YachtFund

Thats for that Wabbit (great name by the way). I'm really after the code to a back test that would do something like calculate the previous days high and low and buy or sell on breakouts. Within that have some optimisations such as buy/sell at 10 pips above/below the high/low and vary stops etc. And all this on hourly charts. I need to read the manual but I thought someone must have this as I believe its a commone strategy. Cheers YachtFund

the formula Ref(h,-1) refers to yesterday's high if used on a daily chart or data , also it refers to last hour high when used on hourly data . So in brief it always reference to previous bar of the periodcity you are using . Regards

Hi I dont understand why this works and what it does:- SOD:=DayOfMonth()<>Ref(DayOfMonth(),-1) OR Cum(1)=2; Is it an if statement? Thanks YF

Thanks wabbit. So if this plots yesterdays high:- SOD:=DayOfMonth()<>Ref(DayOfMonth(),-1) OR Cum(1)=2; { Day's High } Hi:=HighestSince(1,SOD,H); dHi:=ValueWhen(1,SOD,Ref(Hi,-1)); dHi:=ValueWhen(1,dHi>0,dHi); dHi; { <- High: Blue } How do I get it to ignore weekends? I shall read the manual a bit more.

You can if you know what it does and you don't want it.

With the fourm.dll, you can also get rid of the first N/A bar and move the initialisation back to the first bar of the chart:

It's a long story about how the Ref() function will return N/A on the first bar of the chart, but the Cum(1)=2 will return true on the second bar of the chart: This initialises the SOD variable so it returns true to include all the data since the beginning of the chart and before the first time the DayOfMonth() changes.

Hi All,

I'm looking for a N-day breakout expert that would give a buy signal when the close rises above the highest high value over the last N bars and would similarly give a sell signal when the close drops below the lowest low value over the last N bars.
this could be formulated as:
C > HHV(H, N) for a buy signal
and
C < LLV(L,N) for a sell signal
where N can be any normal, arbitrarily chosen, constant lookback period.

my problem is: what if I wanted the lookback period to change depending on changes in volatility?
for example by setting that N = 14* (Long term volatility / Short term volatility)

I thought I could do with:
N:=Int(14 * ( ATR(20) / ATR(10) ));
C > HHV(H,-N)

but I get an error message saying that "This variable or expression must contain only constant data".

I a true beginner, so I would appreciate any help with this.

thanks in advance for any response.
cheers.
