[amibroker] Using Index Data to Adjust Position Sizing

["woodshedder_blogspot" <woodshedder_blogspot@xxxxxxxxx>]

I'm sure this has already been covered somewhere, but the search function is awful and I haven't found anything useful. Feel free to point me to another thread or the manual if what I'm asking has been covered ad nauseum.

What I want to do is use index data, say maybe the SPY/SPX, to adjust position sizes on trades of common stock.

In Tradestation, one just uses Data 1 (could be the SPY) and Data 2 (the stock to be traded).

An easy example of what I want to be able to do is this:
1. if the SPY is above the 50 dma
2. and there is an entry signal on a stock
3. use a full position size
4. if the SPY is not above the 50 dma, use 1/2 position size

I'm not asking for any code, just the basic method of using index data to affect trades.

Thanks!
