This is a light-weight position tool I coded after not finding something similar and that lets you enter the inputs in a way you do that also at your CEX.
You enter:
1. ENTRY price of position
2. TAKE PROFIT level
3. STOP LOSS level
4. Amount of USD you put into the position (aka collateral)
5. Your leverage (10x, 100x or whatever)
The tool then checks if that is a short or a long to show you that with a color and to calculate the profit and loss correctly.
It then shows you the current PnL in % and in USD at the label where you opened the position.
This is a tool for long and short position without the complicated stuff with "pips", "lot", "ticks", "risk" and all the things you typically don't need and mostly don't know about when trading at a CEX.
I made it to see my PnL without having to check in the App of the CEX which is pretty annoying.
PRO users might miss things... the intention was to make it easily to surveil your position without the need for a lot of inputs.
If your position goes into the desired direction you can lift the SL above the entry (if you're long for example), and it then renames to "SL-Profit" because you're in profit then and not in loss... I think there's some nice detail work in it which you hopefully will enjoy.
