@djoffrey Hey, I'm also getting this:

:823: RuntimeWarning: invalid value encountered in double_scalars
XAD = abs(A-D) / abs(X-A)
:946: RuntimeWarning: invalid value encountered in double_scalars
XAD = abs(A-D) / abs(X-A)
:1055: RuntimeWarning: invalid value encountered in double_scalars
XAD = abs(A-D) / abs(X-A)
:1177: RuntimeWarning: invalid value encountered in double_scalars
XAD = abs(A-D) / abs(X-A)
:123: RuntimeWarning: invalid value encountered in double_scalars
XAD = abs(A-D) / abs(X-A)
:1180: RuntimeWarning: invalid value encountered in double_scalars
XCD = abs(D-C) / abs(X-C)

From what I was able to check, it's not compromising my patterns validation. But I would like to hear from you too.

Djoffrey 你好，这是个非常棒的库。

我看了src下面有2个文件，貌似都一样的 harmonic_patterns.py和harmonic_functions.py，以哪个为准

Hello, good time...I changed the exchange, but with this change, no pattern is detected :( Considering that the data is processed well, what is the problem?

self.is_in(BCD, 1.13, 1.168), the fib ratio is wrong

@djoffrey can you help me out? I think discord would be better. But here it is:

I get the price and the timeframe, but every time I try to add timestamp I get lots of errors. Timestamp for each point of the pattern is very important, otherwise I'll get lost. Cant validate etc. I have all the functions built in this example here inside my code: https://github.com/djoffrey/HarmonicPatterns/blob/main/src/harmonic_patterns.py

Please help.

from HarmonicPatterns.harmonic import send_alert, search_function

This example code does not work as harmonic.py file does not exist. Please suggest

if yes then please reach out :-)

Hello,
It gives the following error when running following code:

binance = getattr(ccxt, 'binance')(ccxt_options)
markerts = binance.load_markets()
symbol = 'BTC/USDT'
period = '4h'

ProxyError: HTTPSConnectionPool(host='api.binance.com', port=443): Max retries exceeded with url: /api/v3/exchangeInfo (Caused by ProxyError('Cannot connect to proxy.', NewConnectionError('<urllib3.connection.HTTPSConnection object at 0x7fcdac308490>: Failed to establish a new connection: [Errno 111] Connection refused')))

Can you please help with this?

Hello again,

I need to my own function to interact with predict_patterns function.

I need to find patterns in the making for many timeframes. 4 out of 5 points of a pattern already reached, and the 5th predicted. What part of the code should I use?

Hello.. Very glad when I found this repository "Harmanic patterns". I have one question (perhaps a stupid question):
How can i use this on dataframe??

Man im appreciated for your hard work. Do you have chance to HH- HL-LL-LH like Tradingview script.

Thank you.
