Flags and conditions do both may qualify either as true or false, thus easily tracked using GRAPH, the difference is that a condition is a test between two (sometimes even more) data, such as “close > close[1]” or “close CROSSES OVER Rsi[14]”, while a flag is a signal such as “flag” in this example or “daysforbidden” in some strategies when you do not want to trade or “TradeON” and so on….
In the code
daysforbidden = OpenDayOfWeek < 1 OR OpenDayOfWeek > 5
“OpenDayOfWeek < 1 OR OpenDayOfWeek > 5” is the condition to be checked and you can graph it with
GRAPH OpenDayOfWeek < 1 OR OpenDayOfWeek > 5
it will yieald a True/False logical value assigned to DAYSFORBIDDEN, which is a flag (and you can GRAPH it by itself, without having to write the longer line above), like a traffic lights, they are a flag to signal that some time has passed (the condition previously set) since it changed colour and needs to be changed again, you see the flag changing colour.
It is a common variable that may be either true or false, you can use any name, flag is just a nickname to make it easier to understand that it signals something.
“pi = 3.14” is not a flag, PI is just a common variable holding a numeric value, not a logical value.
The above code could have been written
if time = 210000 then
TradeOrNot = 1
endif
.
//
IF NOT LongOnMarket AND TradeOrNot and time = 143000 THEN
.
.
ENDIF
.
//later:
if time = 203000 then
TradeOrNot = 0
endif
I hope I understood what you meant.
I hope I understood what you meant.
Yes you did!
Thank you for the comprehensive explanation.
I’ve achieved same result in a long-winded way … but I’ll set a flag / signal next time in my coding.

Hello,
Thank you for code on how to get previous day high / low.
But still, I dont understand this line :
ll=close*1000
Why do you set the variable to close * 1000 ?
Thank you,
PS : Nothing is displayed on daily or even lower timeframes. Version is 10.3 and I apply the indicator on the price as recommended. Do you have any idea please ?
close * 1000 is just a way to assign variables all and ll a very high value the first time or whenever they needs to be reset, so that Min() can later assign them a correct value, I prefer writing ll=999999, but both achieve the same goal.
To be able to enter any trade you must launch it from a TF whose candles close on anyone of the times in the strategy. If you refer time 143000, then you can only use a TF <= 30 minutes, if you want to use the Daily TF… you need to change the code but you will probably write another strategy.
Hello,
Sure, for the min() function, I found it out a few minutes after ^^
I changed the hours to use it on DAX :
starthour = 013000
endhour = 220000
But still, even on 30 15 5 min or 1h, notjing is displayed.
I just changed these hours.
Thank you,
You should post your code, so I can replicate it.
Hello,
Here is my code :
starthour = 013000
endhour = 220000
count = today-date
tcondition = time>=starthour and time<=endhour
if count<=5 and count>0 then
if tcondition then
hh=max(hh,high)
ll=min(ll,low)
endif
if tcondition[1] and not tcondition then
drawhline(hh) coloured(0,255,0)
drawhline(ll) coloured(255,0,0)
hh=0
ll=close*1000
endif
endif
return
I think the starthour format is not working…
But I found this approach more satisfying :
Configuration – Plus Haut & Plus bas précédent
It’s beacuse the condition COUNT in line 4 is always 0, since both TODAY and DATE return the same value.
Also, bear in mind that math applied to dates does not yield correct result (as in spreadsheets), TODAY – 30 will not return the date of 30 days ago, if today is 20190220, it will return 20190190.
