I am looking for a simple filtering phrase that can eliminate all the candles with very long Upper Wick/Shadow.

I tried to get (Upper Shadow is shorter than the candle body) using the following phrases, but failed:

(weekly high - weekly close) is below (weekly close - weekly open)

weekly high minus weekly close is below weekly close minus weekly open

can anyone help me?

Thanks

This should work for you. Just set tail_top_true equal 0 to exclude the big top tails. It's currently set to 1 so you can see what they look like.

Fetcher[
/* compute the range */
set{range, high minus low}
add column range

/* compute the tail top */
set{tail_top, high minus max(close,open)}
add column tail_top

/* compute the tail top percent */
set{tail_top_pct_raw, tail_top / range}
set{tail_top_pct, tail_top_pct_raw * 100}
add column tail_top_pct
set{tail_top_count, count(tail_top_pct > 70.00, 1)} /* set tail_top_pct to desired value */
set{tail_top_true, count(tail_top_count > 0,1)} /* count the number of times over the last x days. currently set to 1 day */

/* Include or exclude */
tail_top_true equal 1 /* set to 1 to include - 0 to exclude */
]
