DEFPARAM DRAWONLASTBARONLY=TRUE
LFC=summation[5](close)
I’d like to achieve the same result with the following simple ‘for next loop’instead using ‘summation’ but there is no output using the ‘for next loop’
for i=1 to 5 do
LFC=close[i]+LFC
next
return LFC
The last 5 bars are 0-4, not 1-5 (these are the previous 5 bars).
The problem could be the value returned by LFC, too big to be displayed.
On DAX that would be about 62000 (5 * 12400), but your are not resetting it to 0 at the beginning, so within a few bars that could become a huge number!
Thank you so much for your super fast response!
You are right! I added one reset ahead of the for next loop and it worked.
LFC = 0 //Reset LFC
for i=1 to 5 do
LFC=close[i]+LFC
next

I am guessing that Robert is posting from his phone otherwise he would have done the same!
AhAhAh…. I am indeed posting from my phone!
I have a quick question there.
In the example code below, I do have the following query
for i=8 to 20 do
LFC=close[i]+close[28]
next
return LFC
is close[28] inside the for statement 28 candles from close[0] or 28 candles from “i” or “close[i]” ?
Kind Regards,
From CLOSE[0], it is constant through the loop.
To be from i you’ll have to write 28+i within brackets.

Hi Roberto, I am trying to count the total number of times an event took place in a given timeframe of my chart.
For example I am counting the number of times RSI crossed above 70 and I want that calculation to be applied to any timeframe so from the beginning of time to end of time loaded.
I don’t know how to set the beginning and end of time in a FOR NEXT loop.
Any eloquent way that this can be achieved?
The beginning is always BARINDEX=0.
BARINDEX is the progressive numeber of bars, so you need to do is, from current bar to zero:
Count = 0
FOR i = BarIndex DOWNTO 0
IF Rsi[14](close)[i] CROSSES OVER 70 THEN
Count = Count + 1
ENDIF
NEXT
RETURN Count AS "Count"
But… all the above is not necessary, since any indicator ALWAYS starts from the beginning, so all you want to do is to sum any occurrence of the event:
ONCE Count = 0
IF Rsi[14](close) CROSSES OVER 70 THEN
Count = Count + 1
ENDIF
RETURN Count AS "Count"

hi @ robertogozzi, i want to modify the code such that it counts how many times the RSI crossed over 70 in the last 30 bars. So the count will be a rolling count between period zero until 30 periods ago. Can this be done?
There you go:
x = summation[31](Rsi[14](close) crosses over 70)
X will retain the value you are looking for.
from current bar [0] up to 30 bars ago [30], it’s 31 bars.
There’s not need to use loops here.

thanks Roberto! I did not think of using summation in this context, but that works nicely!
I used this code to also count the number of times the current close was less than prior close, but that doesn’t return the right answer.
x = summation[31](close < close[1])
Have i done something wrong?
What you have coded will compare the current close to the previous close and then the 2nd to last close to the one before that and then the third to last close to the one before that…. and so on and so on.
If you want to compare the latest close to the 30 previous candles then you will need a loop.
x = 0
for a = 1 to 30
if close < close[a] then
x = x + 1
endif
next

thanks vonasi..
the above is part of a wider problem i am trying to code, but with not much success.
I am trying to count the number of times the price changed direction in a specified period e.g. last 10 candles, in other words the number of times the candle colour changed in the last 10 candles.
so for example, if the first 3 candles were green, but the forth was red, then the counter = 1 as that is the 1st time the close went below prior close.
then candle 5 and 6 were both green then the counter = 2 since the close at candle 5 reversed from red (4th candle) to green (5th candle). I don’t want to count the candles when the colour is same, only when they reverse.
Bullish = close > open
Bearish = close < open
Change = (Bullish AND Bearish[1]) OR (Bullish[1] AND Bearish)
x = summation[10](Change)
There you go.
