Average Dollar Price Volatility Exploration-Deel
 
    This exploration is designed to provide the
average dollar price volatility figure in column F.
This will find this figure for all stocks scanned.
It is most useful to apply this just to an exploration
of a small group of stocks. It matches the steps in
Deels book The Strategic Electronic Day Trader.
                   
Col A: day 1    HIGH - LOW   
Col B: day 2    Ref((HIGH-LOW),-1)   
Col C:     Ref((HIGH-LOW),-2)   
Col D:     Ref((HIGH-LOW),-3)   
Col E:     Ref((HIGH-LOW),-4)   
Col F:     (H - L + (Ref(H,-1) - Ref(L,-1)) + (Ref(H,-2) - Ref(L,-2))+(Ref(H,-3) - Ref(L,-3)) + (Ref(H,-4) - Ref(L,-4))) / 5            
  

Average Dollar Price Volatility Indicator-Deel
   
    This indicator plots the value on the chart display.
It is useful only as a quick method of attaching the volatility
value to the stock. Apply this with caution and make sure that
the new scale display is also included.
(H - L + (Ref(H,-1) - Ref(L,-1)) + (Ref(H,-2) - Ref(L,-2))+(Ref(H,-3) - Ref(L,-3)) + (Ref(H,-4) - Ref(L,-4))) / 5

Close Above Median Price

This exploration is designed to find those stocks where the close is above the median price over the past five days. It matches the steps in Dels bvook The Strategic Electronic Day Trader.
col a = CLOSE - MP()
col b = (Ref(CLOSE,-1))-(Ref( MP() ,-1))
Col c = (Ref(CLOSE,-2))-(Ref( MP() ,-2))
col d = (Ref(CLOSE,-3))-(Ref( MP() ,-3))
col e = (Ref(CLOSE,-4))-(Ref( MP() ,-4))
filter = colA>=0 AND colB>=0 AND colC>=0 AND colD>=0 AND colE>=0
    The filter in the exploration only shows those stiocks that have the strongest bullish bias over all 5 days. By removing the filter all stocks will be shown. Ranking the first colum will then allow you to estaboish the overall score for each stock.


MACD Custom

The Input() Function(MSK-man. p.271-273) cannot be used directly in the Explorer (MSK-man. p.351). It is reserved to be used in a custom indicator. However, the custom indicator's default value can be used in an exploration.

Since you have created a {faulty} custom indicator, than just re-code it. By referencing the Input() Function using the fml() CALL Function
(MSK-man.p.226-227 and 208-209 and 212), you can still use its {by you at design time} assigned Default value.

Custom Indicator :
Name: MACDcustom
Formula:
MAprd:=Input( "Periods", 5 {Minimum}, 30 {Maximum}, 14 {Default} );
YourTrig:=Mov( MACD(), MAprd, E );
MACD();
YourTrig

When creating the exploration just click the function button and look under the Custom Indicators heading for both of the above custom indicator functions, and "Open" each of them one by one, to paste them into your column TABs (MSK-man. p.347-348) .

Exploration:
Name: MACD crosses my Trigger
Columns:

Name: Close
Formula:

Colb:
Name: MACD
Formula:

Colc:

ADX And Trendlines

if you want to identify directional movement by expressing that the ADX "is rising" the most basic way to do it would be:

ADX(14) > Ref(ADX(14),-1) -- Today's ADX is greater than yesterday's ADX.

There is another aspect to the ADX that bears investigation, though; namely the level of the ADX. There seems to be a general consensus that an ADX over, say, 30 indicates a stronger trend than lower ADX readings. So you could either write ADX(14) > 30 -- or not, depending on your objectives. You can stipulate that both conditions are true by joining them with the word "and."

Also, I have found the following helpful: try using the custom ADX formula posted on the MetaStock website. Wilder wrote the original ADX in such a fashion that it rounds the readings out to the nearest whole number. The "regular" canned MetaStock ADX does this, while the custom ADX does not. The non-rounded readings are just a shade more sensitive, which can be helpful.

Finding Trendiness

A remark by Chuck LeBeau about trading with the trend has stayed with me. He speaks of the actual strength of a trend as opposed to merely its direction. Entry strategies (pullbacks in his view) should be tailored to both direction and strength, he says. This makes perfect sense to me.

Here are some initial thoughts. Perhaps you can help me to arrive at some kind of "hierarchy" of trendiness, or call it a classification, or a taxonomy,
consisting of both direction and strength. For convenience, I'll describe only long trades.

I. General direction, long term:
EMA(21) > EMA(55)

II. Trend picks up steam:
EMA(13) > EMA(21) > EMA(55)

III. Strong:
EMA(8) >EMA(13) > EMA(21) > EMA(55)

IV. Somewhere between II. and III. the ADX(13/14) usually starts rising. From what I've seen, a rising ADX at any level generally means business:
ADX(13) > Ref(ADX(13),-1)

V. Very strong trend: (this is where Linda Bradford's "Holy Grail" and such kick in)
ADX(13) > Ref(ADX(13) and
ADX(13) > 30

Almost forgot . . . very little direction (but don't fall asleep at the wheel):
ADX(13) < say, 12-15 and has been bumbling along down there for a while (hard to quantify for me to date)

Weakness In A Strong Trend

In an up trend, three or four successive lower CLOSES and the EMA(21) is rising.

SimpleX LONG:

C <= Ref(C,-1) AND
Ref(C, -1) <= Ref(C, -2) AND
Ref(C, -2) <= Ref(C, -3) AND
Mov(C, 21, E) > Ref(Mov(C, 21, E), -1)
OR
C <= Ref(C,-1) AND
Ref(C, -1) <= Ref(C, -2) AND
Ref(C, -2) <= Ref(C, -3) AND
Ref(C, -3) <= Ref(C, -4) AND
Mov(C, 21, E) > Ref(Mov(C, 21, E), -1)

SimpleX SHORT:

C >= Ref(C,-1) AND
Ref(C, -1) >= Ref(C, -2) AND
Ref(C, -2) >= Ref(C, -3) AND
Mov(C, 21, E) < Ref(Mov(C, 21, E), -1)
OR
C >= Ref(C,-1) AND
Ref(C, -1) >= Ref(C, -2) AND
Ref(C, -2) >= Ref(C, -3) AND
Ref(C, -3) >= Ref(C, -4) AND
Mov(C, 21, E) < Ref(Mov(C, 21, E), -1)

Rig this up with an OB/OS oscillator and you've got an entry that is, well, at least worth considering.
