# Help needed understanding candlestick pattern formula

I have a list of formulas for calculating candlestick patterns.

There are a few expressions that I do not know the meaning of.

Here is an example:

Bullish Engulfing

``````O1 > C1 AND 10 * (C - O) >= 7 * (H - L) AND C > O1 AND  C1 > O AND 10 * (H - L) >= 12 * (AVGH10 - AVGL10)
``````

At the very end of the formula `12 * (AVGH10 - AVGL10)` what does `AVGH10` and `AVGL10` mean?

More specifically what does the number 10 represent?

Candles? Or is it just an arbitrary number?

If it is just a number the expression would result in a 0 since we have an average of a single number which would be the number itself, so we would end up with 12 * (10 - 10) = 0. So that can't be it.

In another example:

Meeting Lines

``````C1 < O1 AND H1 - L1 > AVGH21.1 - AVGL21.1 AND O1 < MINL3.3 AND C > O AND 100 * ABS(C / C1 - 1) < 1
``````

Here `AVGH` and `AVGL` are floating numbers.

Additionaly there is also `MINL3.3`. What does `MINL3.3` mean?

Bonus question

Doji Dragonfly

``````50 * ABS(O - C) <= H - L AND STOC1 >= 70 AND H - L >= AVGH10 - AVGL10 AND L = MINL10
``````

What is `STOC1`?

Formulas soruce

Well the answer is partly in the documentation

AVGH10, 10 stands for the previous 10 candles.

STOC1 stands for the value of the 1st line of the Simple Stochastic oscillator

The floating numbers in expressions like AVGH20.1 remain a mystery
