[amibroker] calculating the mean of only some of the observations in an array ?

Without requiring loops that work through the whole barcount, can someone point out to me how to exclude certain values in an array when calculating a statistic across an array? I must be missing something. I am trying to calculate the mean of some values that occur only occassionally (after m

[amibroker] CBT / maintain net exposure close to zero

I am trying to figure out how to get the custom backtester to take only buy signals when greater than 5% net short and take only short signals when I'm greater than 5% long. I recognize that is not the best feedback loop required to maintain a "hedge" but for learning purposes, I'm OK with an

[amibroker] ATC question

I would like to write values that change each bar to a "dummy ticker" using ATC. Here in my example, I am retrieving real-time data from eSignal and trying to write it to various fields in a dummy ticker called ~BA (where is ticker). The problem I'm having is that the current values

I am trying to get Amibroker Professional 5.0 while running eSignal to save bid/ask information on 5-second bars to a "dummy" ticker using ATC. What I have written below seems to write (and plot) a cumulative number to a dummy ticker called ~Bid that relates to each sequential bid and ask

[amibroker] Yahoo Fundamental retrieval

I am trying to save fundamental information to non-traded tickers to create a database for later analysis. The approach I have outlined below is to use AddToComposite to "store" various fundamentals each day. This code, instead of storing today's data for today's date only, is storing today's

[amibroker] copying categories from one database to another

I am stumped. Maybe there's a way to do this using menus but i can't find it. I spent time creating custom groups and watchlists and now i want to move a copy of this grouping information to a new database. Does anyone know an easy way to do this? I've started down the path of writing code and

Can anyone tell me what is the difference between these two? I'm tracing and i'm getting different results for different stocks. Thank you! PriceAtBuySignal = ValueWhen (Buy==1,Close); _TRACE("PriceAtBuySignal "+PriceAtBuySignal); PriceAtBuySignal = LastValue (BuyPrice); _TRACE("PriceAtBuySigna
