G'day,
Below is some AFL code I've written to scan for stocks
starting to meet the criteria as set out in Stan Weinstein's book 'The Secrets
of Profiting in Bull or Bear Markets'.
To use it you must have your industries, sectors and indices
set up correctly in Ami.
The code picks stocks to go long on - not stocks to
short.
Also it picks stocks as they enter Stage 1 not as they enter
Stage 2. So it's intended to create a watch list not to be a system. I'venot
included volume as a criteria - I need to understand how OBV works.
If you just want stocks as they enter Stage 2 the line
marked /* Modify */ would need to be changed to
cond2 = close >
ma(close,maLong) AND close > open;
maLong and maShort canbe
modified to suit. The lower the maShort value the more aggressive the Trade.
maLong is probably best left at 150 - but could be changed according to the
market being traded.
dollars is the size of the trade and is to ensure sufficient
liquidity - this is a personal criteria.
Now I have a couple of questions to those
interested.
1. This code checks that the stock is out performing its
sector but does not check the sector is outperforming the market. Can AFL
cater to this also ? If so how ?
2. If the exrem statement is uncommented less stocks are
reported as buys than with it removed. exrem appears to remove <FONT
color=#000000>more than just duplicate buy signals. I'm obviously
missing something.
<FONT color=#000000
size=2>3. How does on balance volume work ? I'd just like to add a check that
white candle days are of higher volume than black candle days over the past
week for example.
Any ideas appreciated,
Geoff
