Doji Question

[RPrado]

I am looking for a way to measure the body height of the 2nd day in the screenshot shaded area. I also would like a way to indicate on the 3rd day (3rd bar in the shaded area) that volume is equal to or greater than the 1st day.
I hope someone can assist, Thanks,

Generally a bodylength can be defined as the following

def bodyLength = absValue(open-close);

For whatever day you're looking for just index it back to the bar you're looking for.

@tomsk I really appreciate the response, but I have simply no skills in scripting. How would a script be to 1st) trigger the momentum on the 1st bar based on its volume, then 2nd) identify the 2nd bar as similar to a "thick Doji", and 3rd) confirm momentum on the 3rd bar with volume at least equals to the 1st bar (day)? Thanks a lot.

 

[RPrado]

note the 1st bar may also be triggered by ttm_squeeze, so I can work with it. My challenge is to spot momentum on the 2nd bar(day) and have a method to confirm momentum on the 3rd. Thanks,

I really don't understand what you are looking for. First you seem to want to compare what appears to be a three day moving candle comparison based on volume without a clear definition/logic of the relationship of volume between those 3 candles. Next you make reference to TTM Squeeze. How are candles related to the TTM Squeeze which is another study? Coding is a very precise activity. Suggest you be real clear in your goal, as I don't do piecemeal requests

RPrado, check out the utube video.
It might help you with what you are looking for.
i belive he uses "9 EMA" and the 3rd day to confirm buy signal.

@Johnny Cash thanks.

I appreciate the honest criticism @tomsk. I will elaborate the description to what I whink will make sense for coding. The 1st day candle height and volume dictates the potential price movement on the 3rd day. The doji like candle in the 2nd day is to be used as trend confirmation and ideally the doji like must open equals to or higher than the 1st day close. The 3rd day candle height has an expectation of running as high as the 1st day, but it is not a guarantee but probability. So, on the 3rd it's expected a volume at least equals to the 1st day candle. A position is taken once the 2nd day doji like confirms trend.

In addition, just to explain my ttm_squeeze mentioning, I use it to scan potential setups for the strategy above.

I hope this is more clear and that you or someone else experienced in coding may be able to assist. Many thanks,

@RPrado

It was not a criticism, too often I have seen cases where very loose and imprecise requirements make it difficult to code
That's why you need to be real precise and spell things out explicitly.
Here's what I understood from your rather expanded message.

Day 1 - note the body height and volume
Day 2 - doji - opens at or higher than Day 1's close
Day 3 - volume greater than Day 1's candle

Your explanation while better than the first time round you attempted to do so is still loose
Day 2 doji to me means open and close is the same price. Doji-like to me is not precise enough.
Day 3 candle - there is no mention whether the candle opens/closes up or down relative to candle 2

Hence you need to spell things out explicitly as coding is a very precise activity

 

[RPrado]

@tomsk Very appreciated. I will elaborate further later today. Many thanks.

@tomsk The chart below is today's price action in SHOP. I am currently following it to determine if it will form a doji like candle today, which would be 2nd day of this strategy. Ideally, the doji like candle is small in body height, opens above 1st day, and close is below the 3rd day candle open. So, the ideal 3rd day is to open at or above the 2nd day doji like close. I share today's SHOP chart which is supporting this strategy. Thanks,

 

[tomsk]

While this is a better definition for day 2 and 3 you have yet to define how you plan to use the information from day 1's body info.
Until you can have a clear definition in that regard, I can't help you.

The rules for day2 and day3 as you've defined are relatively straightforward and can easily be coded
BTW, SHOP did not close a Doji today

 

[RPrado]

Hi. I followed SHOP and had positions on it. Yeah, it did not form the 3rd day for profit. The volume we observe in the 1st day is to be used as guidance on the 3rd day as to whether it will complete the 3Bar. We know SHOP did not. So on the 3rd day we’d expect volume to be equal to or greater than 1sr day. I keep thinking if there’s a better way to track 3rd day, and perhaps you may have better ideas, which I’d also be grateful for. Thank you so much for your support and interest. 😊

 

[RPrado]

@tomsk Hi. I hope this updated may help to consider a potential script. So, the 1st day has a massive volume and its volume is to be used as a guidance on the 3rd day to measure the success of the strategy. It is not mandatory, but simply to gage how much volume is to be expected on the 3rd day. I think we have a clear idea of the DOJI like candle on the 2nd day = Day 2 - doji - opens at or higher than Day 1's close. In addition, we must use TTM squeeze as a trigger for entering a position. So, having the DOJI like candle formed, we also must verify a trigger on TTM squeeze. Once it goes 1st day green as shown below it's time for the trader to consider taking a position. So, in summary it's the DOJI like formation and TTM squeeze which together inform the trader of a potential long entry.

I hope this helps and let me know if anything is not clear enough. Thanks a lot,

@tomsk @BenTen here is the result of the 3bar play I did on GOOGL.

So I am new here and figured I would contribute a little something...This is a simple script that looks for a doji with a tail at the bottom of a downtrend, the tail usually signifies it dipped enough to wipe out stops then with the liquidity shot back up good way of spotting the bottom you can also use it in a scanner just add it as a custom study and select the plot 'Bullish' and the value to be true.

I use it at the end of the day/week/month but you could use it on shorter time frames no repainting either so the signal is reliable to find the pattern but should be used with other indicators for confirmation. I like this study b/c it doesn't rely on any math or MA's it is looking for a bar pattern which is pretty unique for most studies...

Here is the code in action...it doesn't catch them all but it is a rather simple code...

#shadow factor looks for tails based  body height of the candle in a downtrend  the idea was to find tails at the bottom of downtrend setup signifying liquidity being bought

input downtrendSetup = 6; #Number of bars to calculate downtrend slope...not all of these bars have to be descending as long as the overall value is neg it is descending

input shadowFactor = 1; #size of tail in relation to body  higher number less signals can be like .50 for more signals just not below zero or zero


assert(shadowFactor >0, "'shadow factor' must not be negative or zero: " + shadowFactor);

def BodyHeight = BodyHeight();

plot Bullish = IsDescending(close, downtrendSetup) and low<low[1] and low[1]<low[2] and low[2]<low[3]
    and
    Min(open, close) - low > shadowFactor * BodyHeight;

Bullish.SetPaintingStrategy(PaintingStrategy.BOOLEAN_ARROW_UP);
Bullish.SetDefaultColor(GetColor(4));
Bullish.SetLineWeight(2);

The latest version of TOS? seem to have an option to change the color if the candle is Doji on Appearance tab for the chart settings. Would that replace this indicator?

Indicator colors override system appearance settings...

 

[jcsantiago1]

Is there a reverse version of this on the bearish side?
