Your code	Documentation
double SlowMovingAverage = iMA( Symbol(), 0, MASlowPeriod, 0, MODE_SMA, PRICE_CLOSE, 0 );	int  iMA(    string               symbol,            // symbol name    ENUM_TIMEFRAMES      period,            // period    int                  ma_period,         // averaging period    int                  ma_shift,          // horizontal shift    ENUM_MA_METHOD       ma_method,         // smoothing type    ENUM_APPLIED_PRICE   applied_price      // type of price or handle    );

Perhaps you should read the manual, especially the examples. They all returns a handle. You use the handle, shift and count to get the data.

In MQL5, the handle of the indicator is received ONE time (in OnInit) and then used CopyBuffer (to receive data from the indicator). Example:

I showed you how to create an indicator in MQL5. But you can continue to make a mistake and continue to watch video in MQL4.

iMA does not return a double. #1

your right.

thanks.

can you advice me how can I find Slope of line for moving average curve.

my strategy is : when Slope of line of moving average curve change from negative to positive, this is a buy or sell time. 

[William Roeder]

Slope = Δ Price × Δ Time
