need help on programming 2 SMAs on an indicator

Hello,

New to programming MT4 and am struggling on the declaring my variables.

What I want to do is have an external input for 2 simple moving averages, then compare them to one another, if I get a long signal, I want an up arrow and if a short sognal a down arrow (of course).

When I go to compile, I get an error that I have not defined the the MA's correctly. My syntax is messed up or it could be in my IF statement as an example for my fast moving average = F_MA and I have a statement (F_MA(2) < F_MA(1))...what I am trying to do there, is if the fast ma of 2 bars ago is less than the last fast ma bar ect...I could be completely off there also...

I have been searching for other indicators that I can look at and see what I am doing wrong and am not seeing anything as basic as what I want to do...any thoughts or directions would be appreciated.

change it from (1) to [1] and (2) to [2]

Thank you, that took care of one thing, I wanted to search before I asked my next thing...I guess I know enough to be dangerous

I guess I am not declaring it properly because now I am getting an unexpected error on the square brackets. Below is how I am declaring the fast ma, and below that is part of the if statement, I just want to compare the latest closed bar with the bar before, that is all and I thought I could use prevBar[1]and prevBar[2] but I cant find that in the manual...

double F_MA = iMA(Symbol(),0,("+FAST_MA+"),0,0,PRICE_CLOSE,0);

if ( (F_MA[2] < F_MA[1]) && (S_MA[2] <= S_MA[1]) || (F_MA[2] <= F_MA[1]) && (S_MA[2] < S_MA[1]) )

Well, I went back and read some more and I think I got it...only now I dont get no errors, but when I try to load the indicator after compiling, it wont load, so now on to the next thing haha!

This is what I ended up doing, not for sure if this is the neatest way I could do it, just declared 2 fast MA's and that seemed to fix the error...



double F_MAa = iMA(Symbol(),0,("+FAST_MA+"),0,0,PRICE_CLOSE,1);
double F_MAb = iMA(Symbol(),0,("+FAST_MA+"),0,0,PRICE_CLOSE,2);
