Is This An Engulfing Indicator?

[Lone Wolf]

If possible I would like to modify this so that the candle on the right shows an en engulfing candle as well.

Please post the code from the related study so we can look at it. Otherwise, it's hard to know what is wrong or what needs to be fixed.

I cant get any other code except this.

For some reason it doesn't show up in the study section for you to view the code.

if you don't know where to look for the study code, there is no point in altering a code for you. you need to do some studying.

why are you looking at a web page? are you using a built in study? what is the name?

regarding post1, we don't know what candle you are talking about,
candle on the right... right of what?

if the purple arrow is pointing at an engulfing candle, then it must be based on body size and have to be bigger than the previous one.
maybe the other candle has a top level equal to other candle , instead of greather than?

for some reason it doesnt show up so that I can view the source code. I cant search for the indicator but I can only select it.

From what I can tell from this screenshot and your screenshot of the parameters, it looks like you're trying to use the "Engulfing" candlestick pattern that's built into TOS. If you right-click and select "view" on that study, you'll see this:

def BodyMax = Max(open, close);
def BodyMin = Min(open, close);
def IsEngulfing = BodyMax > BodyMax[1] and
    BodyMin < BodyMin[1];
def IsWhite = open < close;
def IsBlack = open > close;
def IsPrevDoji = IsDoji(length)[1];

plot Bearish = IsAscending(close, trendSetup)[1] and
    (IsWhite[1] or IsPrevDoji) and
    IsBlack and
    IsEngulfing;

plot Bullish = IsDescending(close, trendSetup)[1] and
    (IsBlack[1] or IsPrevDoji) and
    IsWhite and
    IsEngulfing;

If you look at the definition of the IsEngulfing parameter, it requires a bearish engulfing candle to have an open greater than the open of the previous candle, and a close lower than the previous close.

Your screenshot is very zoomed in so I can't tell for sure but it looks like the open of the engulfing candle that you want is lower than the open of the candle before it, which is why it's not getting flagged here. If you wanted to fix this, you'd have to copy the code in the study and adjust it yourself or look at some of the existing studies on this website that detect engulfing candles.

This is the only way i can find the engulfing study on my TOS.

It does not allow me to right click on it.

Additionally, when I drill down and try and search for the study, it does not show up.

under Patterns, select candlestick, find engulfing and you can then add it. It will show you an arrow like a study. also, you can copy the code and then in the scanner you paste it as a custom study

sorry if i came across a little aggressive in first post.

thanks to FSUTommy, i found the pattern code and studied it.
to answer your question, some bars are not marked as engulfing, because the study is looking at 3 additional conditions to the engulfing condition. if price levels are not smaller, then it did not mark it as engulfing.

i copied the pattern code and added some inputs to choose conditions to apply (in the plot formula).
with all 4 set to no, i think you will see what you expect, just the engulfing rule.

input engulfed_bars_have_to_be_smaller = no;
input use_rising_falling = no;
input use_white_black = no;
input use_PrevDoji = no;
