Hi chi, Brief responses to your questions (the markets are open & I'm trading, so not much time for detail):
1) Yes. See Foreign in help and numerous posts in this group. 2) Yes. AB is very programmable. If you can think articulate it, it probably can be done. 3) Try this to get started: Buy = C> MA(C,65) AND REF(C> MA(C,65) ,-1) AND REF(C> MA(C,65) ,-2); Peace and Justice --- Patrick ----- Original Message ----- From: jchi18 To: [email protected] Sent: Tuesday, March 09, 2010 6:22 AM Subject: [amibroker] AFL Programming Questions Now that I've found a competent group that seems willing to help, I would like to pose some questions: 1. What is the best way to reference an index (i.e., S&P 500) and depending on the condition of that index the formula would indicate a buy signal for stock A or a sell signal for stock B? I am trying to create a simple formula that trades two ETFs (MDY for longs and MYY for shorts). 2. Is there a way to change your position size depending on variables? For instance, I would like to increase the size of my buys and decrease the size of my shorts in the case where the overall market (i.e., S&P500 close > its 200 MA) is in an uptrend. And vice versa. 3. I have been reading some books and I wanted to emulate a formula that I read about. It's very simple but I can't figure out how to do it simply. If there are three consecutive closes above the 65 SMA, then buy. If there are three consecutive closes below the 65 SMA then sell. Any thoughts on how to do it? Thanks again for everyone who helped me before. I'm going to guess that you'll be hearing a lot from me. ------------------------------------ **** IMPORTANT PLEASE READ **** This group is for the discussion between users only.
