Setting a Stop loss and target in a strategy (missing piece in a sample)

[Usct]

Hi,
I want to test a simple strategy with

1. Signal Generation ( many examples available)
2. Set Buy/Sell order (examples available)
3. Set Stop Loss and Profit Target (Couldn't find this piece, closest was https://github.com/mementum/backtrader/blob/master/samples/order_target/order_target.py
   but the stop loss piece is missing, please advise.

Stop Loss could be : Based on ATR OR Based on fixed value/percent of price etc.
Profit Target could be : Based on Fixed value/percent, price of an instrument etc.

For example:
The Buy Signal is generated at price of $100:

1. Enter the trade by buying at $100 or better, set a stop loss of $90 and Target of $120
2. Exit if Stop Loss is hit, i.e. price moves below $90 OR Exit if Target is achieved, i.e. price moves above $120

The Sell Signal is generated at $100

1. Enter the trade by Selling at $100 or better, set a stop loss of $110 and Target of $80
2. Exit if Stop Loss is hit, i.e. price moves above $1100 OR Exit if Target is achieved, i.e. price moves below $80

Thanks

Such a sample already exists. It is ATR-Based

See: https://www.backtrader.com/blog/posts/2016-07-30-macd-settings/macd-settings.html

(Of course, it is included in the sources)

Thanks a lot!
Somehow it was not showing in search results and the code on git repo didn't have init part where all the magic is happening

[backtrader]

Checked the repository and the strategy in the aforementioned sample has a complete __init__. Should there be a problem, don't hesitate to share the details.

Ok I got it,
This source has complete code (and I couldn't find this earlier)
https://github.com/mementum/backtrader/blob/master/samples/macd-settings/macd-settings.py

While this one which has same comment in strategy def, doesn't have init part
https://github.com/mementum/backtrader/blob/master/samples/order_target/order_target.py
may be this is meant for something else
Thanks for such a prompt and highly useful response

@Usct

order_target_percent is not aimed at stop-loss. The order_target_xxx family of methods allow to size an order using for example expected value or percentage of value but don't set stop losses.

There is no need for __init__ in that sample. The logic for the orders is 100% in next and is explained here:
