Calculate cumulative sum from session start

(login for full post details)

Hi,

is it possible for someone to help me get the cumulative sum from start of the trading session/or if easier from specified starting time?

i will be using it for stocks (so I won't be having issues with different trading session starts). For instance, I just need to get the logic correct so I can use it in my testing.

for instance, if I want the cumulative sum of upticks from start of the session:

HTML Code:

inputs: sessionStart(1530), sessionEnd(2200),length(9);

var: cumupTicks(0);

if Time >= sessionStart and Time <= sessionEnd then 
    cumupTicks += Upticks  else cumupTicks = 0;


plot1( ccumupTicks , "Cumulative Upticks", Green );

or is it better to do:

HTML Code:

inputs: sessionStart(1530), sessionEnd(2200),length(9);

var: cumupTicks(0);

if Date <> Date[1] then 
    cumupTicks += Upticks  else cumupTicks= 0;


plot1( ccumupTicks , "Cumulative Upticks", Green );

Or How should it be? I appreciate any help.

Thanks in advance

I am answering in relation to Multicharts Power Language:

will NOT work -------------- cumupTicks += Upticks else cumupTicks = 0;

will work -------------------- cumupTicks = Upticks + cumupTicks[1] else cumupTicks = 0;

Now, in regards to your question of date vs session start, they both should work but which one is more efficient is unknown to me.

I have always wondered if there is a way to catch how fast an indicator executes - something similar to Excel VBA where you can actually measure the execution time.
I would be very happy if someone knows how to do this.

Thanks a lot for taking the time to answer, Appreciate ur help. Just 1 more thing, wouldn't ur code cumupTicks = Upticks + cumupTicks[1] only sum the prev's bar tick instead of accumulating the values from count of 0? or have I misunderstood the logic?

No, this will do the cumulative.

At bar one (1), cumupTicks[1] is zero so
cumupTicks is = Upticks + 0 ;

At bar two (2), cumupTicks[1] is = Upticks[1] so
cumupTicks = Upticks + cumupTicks[1] or
cumupTicks = Upticks + upTicks[1]

At bar three (3), cumupTicks[1] is = Upticks[1] + Upticks[2] so
cumupTicks = Upticks + cumupTicks[1] or
cumupTicks = Upticks + Upticks[1] + Upticks[2]

and so on
