Task: there are two iMA indicators. Need to find: how many bars have passed since the last crossing.
Algorithm: if this is the first run - use the first form of the CopyBuffer function
Call by the first position and the number of required elements
intCopyBuffer(
int indicator_handle, // indicator handleint buffer_num, // indicator buffer numberint start_pos, // start positionint count, // amount to copydouble buffer[] // target array to copy
);
copy 100 elements and search for the intersection. We print the number
of the bar and the opening time of the bar with the
intersection
for(int i=1; i<count-1; i++)
{
if((fast[i+1]<slow[i+1] && fast[i]>slow[i]) || (fast[i+1]>slow[i+1] && fast[i]<slow[i]))
{
Comment("Bars after the last iMA crossing: ",IntegerToString(i+1)," (",TimeToString(rates[i].time,TIME_DATE|TIME_MINUTES),")");
m_last_crossing=rates[i+2].time;
return;
}
}
Next time we use the third form
Call by the start and end dates of a required time interval
intCopyBuffer(
int indicator_handle, // indicator handleint buffer_num, // indicator buffer numberdatetime start_time, // start date and timedatetime stop_time, // end date and timedouble buffer[] // target array to copy
);
Counting of elements of copied data (indicator buffer with the index buffer_num) from the starting position is performed from the present to the past, i.e., starting position of 0 means the current bar (indicator value for the current bar). When copying the yet unknown amount of data, it is recommended to use a dynamic array as a buffer[]...
An example of how to create a handle to the MACD indicator. An example of how to get the MACD indicator values on the last three bars. Remember
the main rule: you need to create an indicator handle once (the best option is to create a handle in OnInit).

Open position every new candle.
First we define a new bar.
If this is a new bar - open a BUY position with a minimum volume.

Do not forget the rules: create the indicator handle ONCE in OnInit, use CopyBuffer to get the data.
