Hello,
The following should do the work. It checks the lookback-day
change in price and volume.
If both are positive then "1" is the result, otherwise -1.
Then such binary signal is summed up over period-bars.
Lookback = Param("Change lookback", 1,
1, 100 );
ChgPrice = ROC(
C, Lookback );
ChgVolume = ROC( V, Lookback );
BothUp = IIf( ChgPrice > 0 AND ChgVolume > 0, 1, -1 );
Period = Param("Sum period", 25,
1, 100 );
Plot( Sum( BothUp, Period ), "UpVolANdPrice", colorRed );
Best regards,
Tomasz

Subject: [amibroker] (Price * Vol ) as a
new indicator?
Hi, I
am not an IT guy, so it is rather hard for me to learn AFL and its logic. I am
wondering if someone has written a formula based on (Price * Vol).
Logically,
when Price or Vol goes up, the chart (price * vol) goes up too, so this
is a buy or uptrend signals. The reversal would be when price or volume goes
down. I am wondering if the crossing of MA (Price*Vol) of 2 different period,
would be buy or sell signals. Sometimes the peak of the chart happens when
price keeps going down, eventhough the volume goes up (when "big guys"
exhausted to keep price from falling). This is should be strong a reversal
(sell) signals.
Frankly,
I dont know how to put my idea into AFL. Can someone formulate my idea into
indicator and explorer for all of us?
Regards,
kethek
