Hi again. Thanks for input.
I have recieved this as pseudo code. And I am a newbie at python this was the pseudo code:
PSEUDO Code:
1) Initialize State Counter
First we want a counter that counts the hours for our angle calculation. Therefore we need a counter that we can initialise in the state of the bot.
At the start of the bot the counter is zero.
def initialize(state):
state.counter = 0
2) Define Scheduling:
You could schedule your bot every hour
@schedule(interval="1h",
symbol="BTCUSDT”)
3) Define the Handler
1) increment the counter until it is 4 and reset:
If state.counter < 4:
state.counter += 1
Else:
state.counter = 0
2) calculate angle if counter == 4: (every four hours)
- First get your signal line:
macd = data.macd(12,26,9)
signalLine = macd[‘macd_signal’]
- Check if bot has position
has_position = has_open_position(data.symbol, truncated=True)
- Calculate the angle:
This can be a bit tricky here. First representing the signalLine as a straight line is only an approximation.
Probably the easiest way is to calculate the slope of the last four candles and use numpy arctan to convert to the angle.
Here is sample I just did which should get you started:
import numpy as np
def initialize(state):
state.counter = 0
@schedule(interval="1h", symbol="BTCTUSD")
def handler(state, data):
angle = 0
macd_ind = data.macd(12,26,9)
if macd_ind is None:
return
signal = macd_ind['macd_signal']
has_position = has_open_position(data.symbol, truncated=True)
balance_base = float(query_balance_free(data.base))
balance_quoted = float(query_balance_free(data.quoted))
buy_amount = balance_quoted * 0.80 / data.close_last
plot("signal",signal[-1],"BTCTUSD")
if state.counter < 4:
state.counter += 1
else:
state.counter = 0
if state.counter == 4:
lastsignals = signal[-4:]
# calculating the slope of last 4 candles
slope = (lastsignals[-1] - lastsignals[0]) / 3
angle = np.rad2deg(np.arctan(slope))
print("slope: ",slope)
print("angle: ",angle)
plot("angle of signal",angle,"BTCTUSD")
if angle > 30 and balance_base<buy_amount:
print("-------")
print("Checking for buying possibility of {}".format(data.symbol))
print("buy amount:",buy_amount)
print("buy price:", data.close_last)
create_order(symbol=data.symbol,amount = buy_amount)
elif angle < -30 and has_position:
print("-------")
print("Checking for selling possibility of {}".format(data.symbol))
print("sell amount:",balance_base)
print("sell price:",data.close_last)
close_position(data.symbol)
I have a new error message:
> Engine error: File "bot.py", line 13.
> Engine error: @schedule(interval="1h",symbol="BTCUSDT”).
> Engine error: ^.
> Engine error: SyntaxError: EOL while scanning string literal.

@schedule(interval="1h",symbol="BTCUSDT”)
^
SyntaxError: EOL while scanning string literal
I will try to go through some introductionary courses in python to understand the BBCode later. I am just trying to set up a trading bot on the site trality.com
