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.

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:
