hi
how to express the value of tick in script
i used
if (Close[CurrentBar] > Close[CurrentBar-1])
but it is not correct
is this certaian price type to express tick value and volume and time

[ahmedallam]

nellymnumberingstringseries.Set("m" + m.ToString());
i need to put this value in the previous place of data string
can i use
nellymnumberingstringseries.Set(1,"m" + m.ToString());
coz i tried this but didnt give value to string series on watch
also how to add watch to show value of previous slot of data series during debugging

If u want process data tick by tick this code is correct for 1 tick chart only.
On others chart types u should use this code

        protected override void Initialize()
        {
            CalculateOnBarClose = false;
        }

        protected override void OnBarUpdate()
        {
            // Now we got every tick processing
            if	(Close[CurrentBar] >  Close[CurrentBar-1])             
            {
            }
        }

(Close[CurrentBar] > Close[CurrentBar-1])
first expression Close[CurrentBar] is just the one understood by script
but the second one Close[CurrentBar-1] give same result as the first one
close just work well when i give it numbers only
close[0].....close[1] respectivly
strange feature i think

Hello ahmedallam,

Thanks for your post.

As member ren37 advised, using CalculateOnbarClose = false will allow you to process tick by tick but this would be on live data only (From a live data feed or market reply).

When using Close[] the index reference[] is to "bars ago". So an index of [0] would mean the currently forming bar on the right edge, while [1] refers to the prior bar, [2] the bar before that, etc.

CurrentBar is a variable that holds the count of bars on the chart. If you have 1000 bars then CurrentBar would hold the value of 1000. If you use Close[CurrentBar] then the close value would be from 1000 bars ago.

thanks for ur reply
ı benefıted much from ıt
but new questions arise
close [the index ref]>>does this reference have to be number only??
can i use a variable to int or double or float?
can i use expression like close[a-b]???
and afterwards can i use certain index to get data from other dataseries on the same bar>>>>>meaning can i make say 4 data ..string..bool..float series and use the index reference in one of them to get to other series and get data at this specefic index????

Hello ahmedallam,

Thanks for your reply.

If you check the Helpguide reference for Close you will see that the BarsAgo is to be an int value. You can perform any math inside the index [] you wish as long as it resolves to a legitimate barsago value. Yes, you can use a variable in the index. Yes, you can use the same reference in other methods, for example:

int signal = 4;

int signalHigh = High[signal]; // get high 4 bars ago
int signalLow = Low[signal - 1]; // get the low 3 bars ago
int signalRange = Range()[Signal + 1]; Get the range of the bar 5 bars ago
