OP,
In the spirit of Baron responded to this thread
https://www.elitetrader.com/et/threads/is-this-what-et-has-become.323091/ I gave you my version of how to learn about & implement stop loss & target
1. Stop loss
It depends on the swing of your trade on the x axis whether it's time base, volume base or whatever you are using to fit your risk objective. Beware that stop loss runners are aware of the location of stop loss. They are very obvious on the chart. You should be able to learn to run excel program to determine your instrument's swing statistic. You also should be able to have statistic based on your entry's precision and from those, you better dig deeper on how to improve your entries.
*My stop loss is mainly for emergency only like lost connections, exchange shut down, quick swings due to immediate news etc. I day trade CL mainly 6 ticks stop loss & if it hits 3 ticks against me, I'm out. There are people I know who have even tighter stop loss (3 ticks in CL) but they are the true masters.
2. Target
In general, target is also depending on your swing strategy very much like stop loss but in the opposite direction with a twist, not as R/R as if market will obey and honor your plan. It just doesn't give a damn about your plan so prepare to adjust. Take what you can when you can. Depending on your strategy, you should be able to read whether at certain area, it will continue or reverse or fix target based on scalping swings. You need to work on this & it will take time.
*Some people trade both sides of the market at the same time as runner/scalper & each leg has different target but the stop loss is always the same. Simple trader like me couldn't handle both at the same time so I pass. You also should be able to build a statistic table of how good your exits are & reevaluate. Best way to do is find some free program like OBS to record your trading session & replay it to learn.
I purposely write like this so if you want to learn you have to search for it. All the keywords are there for you to work on it. Good luck.
