So lets say price change I estimate will be 0.20-0.25 and my goal is to make 1%-1.5% of my balance (the more the better of course but dont wanna get greedy), does this thought process work?:

3) I usually never risk slightly more than 1% of my whole account, so I'll set SL to slightly below 2% / 10 (0.20%) against my trade, which makes it a 0.75% risk in case of half account margin.

I'm a little bit confused, if you are targeting to make a 1%-1.5% of your balance, so on your every trade, you are trading you all entire balance, right?
If this so, as long as you have your always stop loss or you don't trade with multiple open positions at the time, it's still good and found out you do some scalping with lower time frames.
I like your risk management, it seems that you are not so greedy with every trade you do, just keep it up. My piece advice is much better if you will allocate some percentage(%) of your available balance for your every trade because what if you found some much better and smooth trade setup with other pairs? Since you already have an open position and your balance on that pair.
And about your stop loss, it is the stop market or stop limit? Just remember if you do stop-limit, it is prone to stop-slippage and when yo do stop-market, the fee is quite huge

It is stop market yes. I am scared of unreliability for stop limit.
And yes in my particular example provided in post I was talking about using 50% of balance
