Some brokers like hfm etc offers leverage of up to 1:400 on regular and 1:1000 on micro accounts while some crazy offers in the market like 1:3000 which seems pretty unrealistic to me. New traders being unaware of the market conditions should keep the leverage low because it may bring damages as well.
Demo accounts can be helpful in knowing the processes without depositing any money with the brokers and if finalize the right one always go with small to further test the processes like withdrawal etc which usually can't be tested on a demo.
Some new traders lose money and then blame their brokers for spiking their stop losses which maybe true or might not because when we don't know what we are doing in the markets how can we blame anyone of our losses.
Major pairs are usually high liquid with average or competitive spreads as compared with the other exotic pairs so the new traders should better choose the majors in the early stages of their development.
Based on the analysis, we are putting in pure work and experience to risk our money for making more money from forex trading however speculations are for the gamblers only who are prone on luck only. They may win once which is mere coincidence.
Almost every major broker like hfm, octa, xm, exness, lmfx etc offers news trading with average or competitive spreads and can be used for scalping in my opinion.
The fear and greed can only be overcome by trading a demo and having a proper trading plan so if the goal is achieved or not we should not do over trading and rather review our performance for improvements.
