I'm trying to optimize my strategy on Backtrader with python but keeps getting this error and i can't find anything on the web showing why I'm getting it. My code is simple and loosely based on the quick start examples:

I'm trying to make a trading bot and am using backtrader for the same. I have been trying to debug this issue but couldn't find a solution yet. The code is as shown below

I just switched from Matlab to python and even newer to the backtrader library for backtestingtrading strategies. My questions might seem obvious.

My problem seems similar to this : https://community.backtrader.com/topic/2857/wanted-exit-long-and-open-short-on-the-same-bar-and-vice-versa

and this : https://community.backtrader.com/topic/2797/self-close-does-not-clear-position The code below is a simple MACD strategy. Here is the code :

Can API be used to replace SMTP for mail sending in Django especially for things like reset password and mail confirmation.

I will really love if I can get clarification on a topic in django. I am a newbie to django and when it comes to sending mail I register for Mailgun and used the API since I have used requests before but picking up django to work with I am trying to do user registration using DJ-Rest-auth and django_allauth and there is thing about configuring email backend using SMTP.

my question is

• Can i do without using SMTP for django_allauth if Yes a workflow how to connect my password reset to use the api for mail.
• I can easily pass in the mail function to serve as an alert in the views when user registers

I know I can send mails using django but things like reset password that has a uuid attached to it how can I go about it using API's

I'm trying add a navbar with links that should be below a logo text and centered. However I can't get it to work properly in tablet/mobile view. I have a mockup to follow and have to use only HTML & CSS. I have tried push it with margin & padding but can't get it to be in the center.

Help appreciated.

I need to import several timeframes into a single trading strategy and I am unsure how to proceed.

Here is my data:

I am quite new to R. I have a hospital dataset where patients are assigned categories based on diagnosis. For example

• Patient# : Disease classification
• 1 : dis A/dis C
• 2 : dis B
• 3 : dis A/dis B/dis C

And so on with 8 diseases in total. The "/" here represents the presence of more than 1 disease. I want to categorize them numerically such that dis A=1, dis B=2 and so on. The above data needs to be:

• Patient#: Disease classification
• 1: 1/3
• 2: 2
• 3: 1/2/3

I have tried it with sapply, as a factor with levels but the best I can get is a correct classification with only single diseases. The combination diseases are returning a NULL value. Is there a way to do this? Please help!

Here is a sample:
