I have learn to make crossover of simple Moving average from this thread but i m not able to make DISP moving average crossover AFL..

Easy!!!
Period = Param("Period", 30, 1,200);
Shift = Param("Shift", 15, -200,200);
DISP_SMA = Ref(MA(C, Period), -Shift);
EMA1 = ema(C, 15);
Buy = cross(DISP_SMA, EMA1);
Sell = cross(EMA1,DISP_SMA);

To plot DISP_SMA, do this
Plot( MA(C, Period), "DMA", ColorRed, styleLine, 0, 0, Shift);

regds,

appended the code with buy/sell signal, try this-

Period = Param("Period", 30, 1,200);
Shift = Param("Shift", 15, -200,200);
DISP_SMA = Ref(MA(C, Period), -Shift);
EMA1 = EMA(C, 15);
Buy = Cross(DISP_SMA, EMA1);
Sell = Cross(EMA1,DISP_SMA);

//To Plot DISP_SMA, do this 
Plot( MA(C, Period), "DMA", colorRed, styleLine, 0, 0, Shift);

Buy=ExRem(Buy,Sell);
Sell=ExRem(Sell,Buy);
PlotShapes(Buy*shapeUpArrow+Sell*shapeDownArrow,IIf(Buy,colorGreen,IIf(Sell,colorRed,Null)));

Please help me writing this afl

Scan AFL for NR7 weekly high/low breakout (do not want chart plotting or exploration, only scan needed)

Skeleton

1) Find first NR7 in last 6 days excluding today.
2) Find Highest High and Lowest Low in 7 days of NR7.
3) Highest high or lowest low should not be broken out until today from NR7 day.
4) Generate following signals
a) BUY if today close is higher than highest high of NR7.
b) SELL if today close is lower than lowest low of NR7.

Is it possible to creat an indicator using fundamentals..such as PE ratio?

Yes,it can be done.

c/getfndata("EPS") shall give the p/e ratio.
same can also be viewed in the interpretation window .

Is it possible to create like normal technical indicators?(RSI,STOCHASTIC etc.) and use in normal window not in interpretation.

Help about Message Box

Hi DM,
Thanks and congrats on starting a thread like this. I have gone through almost all the posts in thread.
I have one query about my trading system. I want a message box to be flashed and a beep when buy or sell condition is satisfied. Say for example if Reliance becomes buy then it should flash message like this Reliance is buy. It should also flash the time at which this signal was generated.

Thanks in advance.

Cheers :!!!!!
