Question on MA Shift
I think I got the answer. When I calculate min15ma14now at the start of Bar X, it takes into account the current tick which would be considered the close of the bar X and calculate the MA accordingly. However when I calculate min15ma14prev at the start of Bar X+1, it takes into account the actual close price of Bar X to calculate the MA. The Close price of Bar X will be different at the end of Bar X as compared to the begining of Bar X, hence the difference in the MA's.
Can someone let me know if the explanation is incorrect?
If bar 0 is included in your calculation, then the result is unstable.
I'm not sure what you are saying "exactly", but it seems you are seeing the problem.
The open price will not change.
Now, will you use the open or close of the bar you are comparing with?

I am trying to flag the condition of MA crssover in my EA. For this the code I have written is
min15ma14now=iMA(Symbol(),PERIOD_M15,14,0,MODE_EMA,PRICE_CLOSE,0);
min15ma7now=iMA(Symbol(),PERIOD_M15,7,0,MODE_EMA, PRICE_CLOSE, 0);
min15ma14prev=iMA(Symbol(),PERIOD_M15,14,0,MODE_EMA, PRICE_CLOSE, 1);
min15ma7prev=iMA(Symbol(),PERIOD_M15,7,0,MODE_EMA, PRICE_CLOSE, 1);
cross=0;
if (min15ma7now>min15ma14now && min15ma7prev<min15ma14prev)cross=1;
if (min15ma7now<min15ma14now && min15ma7prev>min15ma14prev)cross=-1;
The above code executes at the start of a new bar and identifies if MA crossover has happened. In the above code shift=1 and shift is MA calculated 1 bar ago in the case above.
However when I look at the result min15ma14prev is not always equal to min15ma14now as calculated at the start of the previous bar. Can someone explain why this would be the case?
