the demo is important no way to ignore but honestly speaking any kind of demo can be useless if there is no focus.
demo account is for beginners to learn and test out strategies. It's recommended to get into live trading asap so you can start learning about proper risk and emotional management as well cause demo won't teach you either of those thing with fake money.
demo is important but the knowledge we take from there actually not works when trading in a real account.
On a live account, trades are executed on the market. On a demo account, they don't. Simulated trading is like a video game you play on your computer. Everything you do in the demo stays on your computer, and the price you ask for is the price you get.
They don't. People who say that that happens are people who see their stop get hit and then price reverses, so they call it "stop-hunting". They call it conspiracy, when it is just coincidence. They never notice all the times it gets to within one tick before their stop and reverses, or two, three, etc. They only notice it when it causes a loss and then purposefully make a mental note of it.
Though the forex market can be manipulated, I think Market makers have no role in manipulating the market. If we look at the patterns carefully and analyse them we can identify the false signals.
Demo and live trading differ from each other. Clearly, if you want to make money, live trading is the way to go. But how will you do it if you don’t have the skills? That’s where demo accounts come into the picture. Both are helpful but on their own terms.
