[amibroker] Coding help request : Sell signal on price fall of certain percentage!

["shahariar4" <shahariar4@xxxxxxxxx>]

I have this code for price percentage change:

Pricechange=(C-Ref(C,-1))*100/Ref(C,-1);

Now i want to set a sell signal that will generate the signal if price falls for more than 4%

Normally it can be done as Sell= -Pricechange>4;

but this code looks into one particular bar to meet the condition but i want if cumulative price fall on some consecutive days is more than 4% then also it will generate the signal.

For better understanding suppose after few days of buy occur, price on 4th day price falls 1%,2nd
How could it be done?

Suppose my buy is Buy= pricechange>5 and V>wma(v,15);
