hello.I try to write a EA using this indicator"LinearRegSlope_V1", but the data which EA prints is different with the data of indicator in the same date and time. parts of my codes are as follows:
this is the input parameters.
enum Applied_price_ // Type of constant
{
PRICE_CLOSE_ = 1, // Close
PRICE_OPEN_, // Open
PRICE_HIGH_, // High
PRICE_LOW_, // Low
PRICE_MEDIAN_, // Median Price (HL/2)
PRICE_TYPICAL_, // Typical Price (HLC/3)
PRICE_WEIGHTED_, // Weighted Close (HLCC/4)
PRICE_SIMPLE, // Simple Price (OC/2)
PRICE_QUARTER_, // Quarted Price (HLOC/4)
PRICE_TRENDFOLLOW0_, // TrendFollow_1 Price
PRICE_TRENDFOLLOW1_ // TrendFollow_2 Price
};
//----indicator parameter
input Smooth_Method SlMethod=MODE_SMA; // Smoothing method
input int SlLength=12; // Smoothing depth
input int SlPhase=15; // Smoothing parameter
input Applied_price_ IPC=PRICE_CLOSE; // Price constant
input int Shift=0; // Horizontal shift of the indicator in bars
input uint TriggerShift=1; // Bar shift for the trigger
this is the call of iCustom. the sequence and type of parameter are the same with the input parameter.
ExtHandle=iCustom(_Symbol,_Period,"Examples\\Test_LinearRegSlope_V1",
SlMethod,
SlLength,
SlPhase,
IPC,
Shift,
TriggerShift
);
the next parts is the essential part.to call CopyBuffer function gets the data of indicator.
double RegSlopeBuffer[],TriggerBuffer[];
ArraySetAsSeries(RegSlopeBuffer,true);
ArraySetAsSeries(TriggerBuffer,true);
if(CopyBuffer(ExtHandle,0,0,3,RegSlopeBuffer)!=3)
{
Print("CopyBuffer from iMA failed, no data");
return;
}
printf("Open RegSlopeBuffer [0] is %f", RegSlopeBuffer [0]);//for test
the question is that the data of indicator shows is different with the data which EA prints. For example,the data which EA prints is
2012.03.19 17:18:02 Core 1 2012.03.01 08:00:00 Open TriggerBuffer[0] is 0.160695
but the data of indicator is -0.051651.
Thanks.
