Just yesterday I read about the Abandoned Baby candlestick pattern. I tried the one SF offers but it didn't seem quite right so I wrote my own. It doesn't specify anything for the most recent day because that's where I expect to see conformation or not in whatever chart comes up.

So why is it frustrating? It's because I tested each line by itself, and each part of the filter, to see if they gave me the results I wanted. They all seemed to work - separately. Put them together and I get nothing. Zip. Zilch. Nada. I did a custom date offset of 40 days, basically two months of trading days (more or less) and every day came up with zero results. I wrote it for bullish patterns but also reversed the aboves and belows to see if it worked for bearish patterns. I did get one result (DRRX, chart date 1/8/20), so I'm pretty sure it's not the filter. I'm just not getting results because the filter is too strict, for lack of a better word. I'll have to keep playing with it I guess.

Anyway, if someone wants an Abandoned Baby filter and feels like tweaking this one, here you go.

Fetcher[/* DOWN TREND */
Show stocks where close 4 days ago was below open 4 days ago
and close 4 days ago was above close 3 days ago

/* DOWN CANDLE */
and close 3 days ago was > 5% below open 3 days ago
and low 3 days ago was above high 2 days ago

/* FIND THE DOJI */
and close 2 days ago equals open 2 days ago
and high 2 days ago was above close 2 days ago
and low 2 days ago was below close 2 days ago

/* UP CANDLE */
and close 1 day ago was > 5% above open 1 day ago
and low 1 day ago was above high 2 days ago

Your filter is too restrictive and it looks like your down candle condition is the biggest choking point.

Fetcher[
/* DOWN TREND */
set{x1, count(close 4 days ago below open 4 days ago, 1)}
set{x2, count(close 4 days ago above close 3 days ago, 1)}
set{x3, x1 + x2}
set{dtrend, count(x3 equals 2, 1)}

/* DOWN CANDLE */
set{x4, count(close 3 days ago more than 5% below open 3 days ago, 1)}
set{x5, count(low 3 days ago above high 2 days ago, 1)}
set{x6, x4 + x5}
set{dcndle, count(x6 equals 2, 1)}

/* FIND THE DOJI */
set{x7, count(close 2 days ago equals open 2 days ago, 1)}
set{x8, count(high 2 days ago above close 2 days ago, 1)}
set{x9, count(low 2 days ago below close 2 days ago, 1)}
set{x10, x7 + x8}
set{x11, x10 + x9}
set{ftdoji, count(x11 equals 3, 1)}

set{tot1, dtrend + dcndle}
set{tot, tot1 + ftdoji}

add column dtrend
add column dcndle
add column ftdoji
add column tot

sort column 8 descending

I think it's too restrictive as well, and I've tried changing to a smaller percentage and still not getting results. I've done some more reading this morning and I think the problem isn't the down candle part but that I'm looking for a doji that gaps below the low rather than the close of the previous candle, and the low rather than the open of the following candle. I'm guessing that it's fairly rare to find a doji that meets those conditions (or gaps up if you're looking for a bearish pattern). I'm going to tweak that first and see what happens.

I do appreciate the input, and maybe I'm missing it, but I don't see your filter looking for an upcandle after the doji.

It is not a fix. All my filter does is show you the hits for each condition set and highlights that your down candle condition very rarely hits, which means that your requirement for all three conditions to hit will very rarely be met.

Yeah, I can see that it's going to be rare. I tweaked it a little and got one result for today, but today's candle didn't continue an uptrend (which is what I'm looking for) so that one won't get my money. It's not the only strategy I'm using, but I like trying different things. If it shows me a result that I like I'll paper trade it for a while. Here's the final version.

Fetcher[/* DOWN TREND */
Show stocks where close 4 days ago was below open 4 days ago
and close 4 days ago was above open 3 days ago

/* DOWN CANDLE */
and where close 3 days ago was > 1% below open 3 days ago
and close 3 days ago was above open 2 days ago

/* FIND THE DOJI */
and close 2 days ago equals open 2 days ago
and high 2 days ago was above close 2 days ago
and low 2 days ago was below close 2 days ago

/* UP CANDLE */
show stocks where close 1 day ago was > 1% above open 1 day ago
and open 1 day ago was above close 2 days ago
