Accumulation Since Signal Function - ACCSINCESIGNAL()

Overview


ACCSINCESIGNAL(Source, Signal)

This function takes two scripts, the first script is the value which is accumulated and the second script is a Boolean value that signals a reset of the accumulation.

This example counts the number of positive days since the first trading day of 2019 using the BARDATE() function:

//Is it a positive day?
V1 = CHANGE()>0;
//Count how many times V1 was true since Jan 2nd 2019;
ACCSINCESIGNAL(V1, BARDATE()==43467)


To calculate the % of positive days in 2019:

//Is it a positive day?
V1 = CHANGE()>0;
//All days will have a price > 0, so this will count the trading days;
V2 = CLOSE()>0;
//Count how many times V1 was true since Jan 2nd 2019;
V3=ACCSINCESIGNAL(V1, BARDATE()==43467);
//Count how many trading days since Jan 2nd 2019;
V4=ACCSINCESIGNAL(V2, BARDATE()==43467);
//Calculate the %
V3 / V4


MFG has had 95 positive days at time of publishing, or 66.4% of the total number of trading days:




Another example:

R1 = RSI() > 75;
R2 = RSI() < 72;
c1 = SWITCH(R1, R2);
c1_on = c1 and (OFFSET(c1, OFFSET=1) <= 0);
ACCSINCESIGNAL(RSI() , c1_on)


This example script would accumulate the RSI values when the c1_on signal changes to a value of 1.
