Op amp driving darlington directly to give voltage regulation. High side current sense resistor connected to instrumentation amplifier built from three opamps , amplifier provides about twice voltage across r sense. ?. feeds into op amp comparator with adjustable voltage think 12 volts or maybe five volts. Anyway when current limit reached opamp pulls voltage opamp down towards ground. Diode included stop current op amp from driiving voltage up and prevent oscillations I guess . Small bulb included to give indication entered current limiting.
Also can see constant current sink using irlz 44 n channel mosfet , op amp here is running off unregulated five volts.
Darlington can get warm.
Resistors are each 10 ohm 7 watt rated.
Designs not too bad really.
Trading stocks typically have the lowest fees on eToro, which is one reason why I recommend you stick to this market when starting out.
All trades charge both a spread and daily rollover fees.
It really comes down to individual trading strategies and preference. But to give you an idea, I tend to hold on to stocks for a minimum of 6 months and all other trades tend to have an average duration of about two-three weeks.
A final word on over-trading.
This is a point that I want to expand on a little more, specifically in relation to copying other traders. Below is a screenshot of my equity chart over six months. The red line shows the number of people copying me.

The same holds true for the stock market in general.
