David,
Having listened to Chris Tate a couple of times
this is my interpretation -
Note - maPeriod is set to whatever period you
want to tradeover. Could be 5 days to 200+ days. You choose the timeframe
you want to trade the stock over. Using ATR means you let the market tell you
when to enter and exist. ie Listen to the market !
Also Note - no use of indicators or oscilators in
the principal selection.
The relative strength stuff is my own criteria -
but Chris does use them as a sluice.
I've also included the BangforBuck stuff to enable
stock comparisons in the great new Explore feature from Tomasz.

maPeriod = 150; /* Say - but whatever you want
*/maRelStr = 5; /* Or whatever - Backtest !! */AtrRange = 2 *
maPeriod / 3; /* Again some suitable fraction to filter out noise - Backtest !!
*/
/* Buy criteria based on MA */
cond1 = close > ma(close,maPeriod) + 0.75 *
Atr(AtrRange);
/* gradient of the relative strength is increasing
compared to its index */
cond2 = ma(relstrength(""), maRelStr) >=
ref(ma(relstrength(""), maRelStr), -1 * maRelStr);
/* relative strength of the stocks index is
increasing compared to XAO*/
indexStr =
relstrength("XAO")/relstrength("");
cond3 = ma(indexStr,maRelStr) >=
ref(ma(indexStr, maRelStr), -1 * maRelStr);
BangForBucks = (dollars/close) *
atr(200);
filter = cond1 AND cond2
AND cond3;

Hi Guy's here my interpretation of one of Chris
Tate's trading methods from his book ...
Have a play and see what you think, whilst it may
have worked for him when he wrote the book markets have changed since 1997 but
it still gives an insight as to what he looks for in a trade ..
May Geoff could expand on his current methods as
he recently attend one of his seminars :)
