Re: [amibroker] MACD Histogram

[wavemechanic]

OK, here is a simplified version that you can add to:

First, let's be clear on your condition.  As I understand, you want to buy when 
have 4 consecutive (I assume) down histogram bars followed by an up histogram 
bar plus MACD() > 0 and RSI() > 30.  If so, cut and paste the following in 
Formula Editor, click Analysis, and Scan.

x = macd();
y = signal();
hist = x - y;
z = hist < ref(hist, -1);
buy = sum(z, 5) == 4 and hist > ref(hist, -1) and macd() > 0 and rsi() > 30;

If you want to see the results graphically add the following and plot to see 
the histogram with buy signals:

color = iif(hist > ref(hist, -1), colorbrightgreen, colorred);
plot(hist, "", color, stylehistogram|stylenolabel);
plotshapes(shapesmallcircle * buy, coloryellow, 0, z);

  Hi Wavemechanic,

  Thank you for your reply.
  I know nothing in programming to know where to put it :(

    Just add something like this properly including your conditions and then 
scan:
    Buy = iif(sum(hist > histprev, 5) == 4 and ref(hist < histprev, -1), 1, 0);
