# Stochastic function is stuck [Python]

can you point me out to what i've been doing wrong?

``````import time
import math
import numpy as np
import datetime
import pandas as pd
import ccxt
exchange = ccxt.kraken()
symbol = 'BTC/USD'
timeframe = '1h'

def get_candle(exchange,symbol,timeframe): # timeframe = 1m 5m 15m 30m 1h 2h... etc.
return exchange.fetch_ohlcv(symbol, timeframe)
ohlcv = get_candle(exchange,symbol,timeframe)
source = ohlcv

def sort_candle_highest(ohlcv,n,z):
i = 0
results = []
while i < z:
series = [x for x in ohlcv]
series = series[:len(series)-i]
hh = highest(series,n)
print(hh)
results.append(hh)
i += 1
results.reverse()
return results
def sort_candle_lowest(ohlcv,n,z):
i = 0
results = []
while i < z:
series = [x for x in ohlcv]
series = series[:len(series)-i]
ll = lowest(series,n)
print(ll)
results.append(ll)
i += 1
results.reverse()
return results
def sort_candle_lastclose(ohlcv,z):
i = 0
results = []
while i < z:
series = [x for x in ohlcv]
series = series[:len(series)-i]
results.append(series[-1])
results.reverse()
return results

def lowest(source, n):
return np.amin(source[-n:])
def highest(source,n):
return np.amax(source[-n:])
class indicators:
print("noerroryet1")
def stochastic_k(source,n,smoothK,smoothD): #for source here ohlcv (get_candle)
print("noerroryet2")
if smoothK > smoothD:
ticksback = smoothK
if smoothD > smoothK:
ticksback = smoothD
def stoch(source,n,ticksback):
print("noerroryet3")
i = 0
close = sort_candle_lastclose(source,ticksback)
hh = sort_candle_highest(source,n,ticksback)
ll = sort_candle_lowest(source,n,ticksback)
print("noerroryet3b")
while i < ticksback:
print("noerroryet3c")
results.append(( 100 * (close[-ticksback+i-1]-ll[-ticksback+i-1]) ) / ( hh[-ticksback+i-1] - ll[-ticksback+i-1] ))
i += 1
print("noerroryet4")
return results

print(stoch(source,n,ticksback)+'lol')
stochastic_k(source,15,1,5)
``````

So im trying to calculate some cool indicators and the function is stuck simply running never ending never printing anything. I have no idea where the mistake is, although its definitely connected with stochastic calculations, i need to get the list of stoch values to than calculate SMA from, i think `[-ticksback+i-1]` should be giving me the correct value in list not sure tho because it wont spit out anything...
