Topic: 2-color Dot Indicator based on an XAVG

Thanks Bruce...you da man!

Topic: 2-color Dot Indicator based on an XAVG
Posted: Wednesday, January 30, 2019 10:42:20 AM

I want to create an indicator (or perhaps it is 2-3 very similar indicators both posted on same chart).

It should print a Green Dot on the chart at the XAVGC17 when XAVGC17 > XAVGC17.1

It should print an Orange Dot on the chart at the XAVGC17 when XAVGC17 = XAVGC17.1

It should print a Red Dot on the chart at the XAVGC17 when XAVGC17 < XAVGC17.1

 

Anyone (Bruce?) know how I can set this up...preferably in v12.6?

Topic: Nested IIF and Greatest Functions
Posted: Thursday, December 6, 2018 8:18:58 AM

I have what I consider to be a complex PCF need.  I think it might be doable using nested IIF and Greatest functions but have not had luck so far.  Here is the logic:

Group A:
A1)  ABS(C2-L1)
A2)  ABS(C2-H1)
A3   H1-L1
 
Group B:
B1)  ABS(C1-L)
B2)  ABS(C1-H)
B3)  H-L
 
Scan1= Largest Group B value is 25% bigger than the largest Group A value 

Scan2= Largest Group B value is 25% smaller than the largest Group A value

 

Can anyone lend a hand?

Topic: Change Indicator Value Size (Font Size)
Posted: Thursday, January 25, 2018 10:13:07 AM

I know how to change Indicator scaling, date value size (to an extent) and price value size (to an extent).  However, I cannot find a way to increase the size of the values displayed for "On-chart" indicators (Such as Fib lines or horizontal lines.

How can the size of these fonts be increased?

Is there a hotkey for drawing horizontal lines?

Topic: v12.6 Wilder RSI Cross in last 3 days
Posted: Wednesday, September 20, 2017 6:49:25 PM

Bruce (et al),

Is it possible to code a PCF (v12.6) to find WilderRSI (10day) crossing above 30 on any of the last 3 days?

I can do it for the current candle, but am not sure how to code offset days in a "from chart" scan.

Any help?

Thanks

Thanks

I&#39;ve resisted moving from 12.6  I may be forced some day.  Until then I&#39;ll look for other options.

Topic: Volatility Stop Flip Within X trading days
Posted: Friday, June 2, 2017 2:11:50 PM

Is there a way to code (or create) a scan for the Volatility-Stop flipping (for example from Bearish trend to Bullish Trend) any of the last say 5 candles?

In other words, I&#39;m looking for a Volatility Stop trend flip within the last week on daily charts.

Ideally, it would be PCF so I can modify the lookback period...but we&#39;ll work with what you can do.

Topic: Zig-zag pcf based off other platform logic
Posted: Saturday, March 11, 2017 6:44:38 AM

I was asked for help converting an indicator used in another platform into a scan pcf for TC2000.  This one is beyond me.  I realize that previous forum posts indicate 1) TC2000 does not currently have a zig-zag indicator and 2) a possibly related indicator from even a different platform was referred to development a few years back.

However, I did not know if anyone had tried to convert this particular 3rd-party code...and whether it might be more doable than the MT version referenced in 2015 and before.  At the very least, I figured it was worth a shot since another TC user had asked me.  So, below are the code for Zig-zag indicator and the function that it calls.

Any shot that it can be converted to pcf?

------------------------

Main script:

input priceH = high;
input priceL = low;
input percentageReversal = 5.0;
input absoluteReversal = 0.0;
input atrLength = 5;
input atrReversal = 1.5;
 
def zigZag = reference ZigZagHighLow(priceH, priceL, percentageReversal, absoluteReversal, atrLength, atrReversal).ZZ;
 
def step1 = open[1] >= open and open >= close[1] and open[1] > close[1];
def step2 = open[1] <= open and open <= close[1] and open[1] < close[1];
 
def upStep1 = step1 and close > open[1];
def upStep2 = step2 and close > close[1];
def downStep1 = step1 and close < close[1];
def downStep2 = step2 and close < open[1];
 
plot UpStep = (upStep1 or upStep1[-1] or upStep2 or upStep2[-1]) and zigZag == low;
plot DownStep = (downStep1 or downStep1[-1] or downStep2 or downStep2[-1]) and zigZag == high;
 

In my mind, this would be 2 pcfs...one for "Upstep Zig-Zag" and one for "DownStep Zig-Zag."  I have taken the step of converting this easier portion to pcf as follows:

UpStep:

(O1 >= O and
 O >= C1 and
 O1 > C1 and
 C > O1)
OR
(O1 <= O and
 O <= C1 and
 O1 < C1 and
 C > C1)
OR
(O2 >= O1 and
 O1 >= C2 and
 O2 > C2 and
 C1 > O2)
OR
(O2 <= O1 and
 O1 <= C2 and
 O2 < C2 and
 C1 > C2)
 
-----------------


DownStep:

(O1 >= O and
 O >= C1 and
 O1 > C1 and
 C < C1)
OR
(O2 >= O1 and
 O1 >= C2 and
 O2 > C2 and
 C1 < C2)
OR
(O1 <= O and
 O <= C1 and
 O1 < C1 and
 C < O1)
OR
(O2 <= O1 and
 O1 <= C2 and
 O2 < C2 and
 C1 < O2)

 

----------------------------------------------------------------------------------------

This is where things get ugly.  The function called above "ZigZagHighLow" contains this code, which is beyond my time and/or ability to convert.

 

ZigZagHighLow function:
 
 
input priceH = high;
input priceL = low;
input percentageReversal = 5.0;
input absoluteReversal = 0.0;
input atrLength = 5;
input atrReversal = 1.5;
 
Assert(percentageReversal >= 0, "&#39;percentage reversal&#39; must not be negative: " + percentageReversal);
Assert(absoluteReversal >= 0, "&#39;absolute reversal&#39; must not be negative: " + absoluteReversal);
Assert(atrReversal >= 0, "&#39;atr reversal&#39; must not be negative: " + atrReversal);
Assert(percentageReversal != 0 or absoluteReversal != 0 or atrReversal != 0, "Either &#39;percentage reversal&#39; or &#39;absolute reversal&#39; or &#39;atr reversal&#39; must not be zero");
 
def hlPivot;
if (atrReversal != 0) {
    hlPivot = percentageReversal / 100 + WildersAverage(TrueRange(high, close, low), atrLength) / close * atrReversal;
} else {
    hlPivot = percentageReversal / 100;
}

Many thanks in advance for my friend.  I wish I could give you more background on the usage of this for trading, but it is not my setup.  However, I will ask the original requester to fill in some detail in this thread.

Thanks Bruce and/or any other person that can help!

Topic: Average including sub-periods
Posted: Thursday, February 9, 2017 9:00:15 AM

I am trying to write a pcf that enures a stock has met avg volume requirements overall for a period, as well as during each of several sub-periods.

For example, day I want avg daily vol >= 300k shares over 90 days as well as each 15day sub-period. ( So there were no periods where volume dried up over the 90 days.)

Here is how I approached it.  I would like Bruce (or whoever) to validate my approach or suggest an alternative if something easier or more elegant jumps out at you.  Thanks in advance.

 AVG(AVGV90.90, 15) >= 300000 AND

AVG(AVGV90.75, 15) >= 300000 AND
AVG(AVGV90.60, 15) >= 300000 AND
AVG(AVGV90.45, 15) >= 300000 AND
AVG(AVGV90.30, 15) >= 300000 AND
AVG(AVGV90.15,15)  >= 300000 AND
AVG(AVGV90, 15)      >= 300000
