You should have started this thread in Forex subforum. It would have gotten a lot more juicy responses.
No it's not. Perhaps you are only aware of scalping being the only way to trade forex but I can assure you it's not.
If you find FX sizing complicated, you should probably go back to study basic math. If your discussion was about leverage, fundamental and technical analysis, forecasting, volumes analysis... then it could make sense. FX sizing is at elementary level of calculation and understanding.
All the "educational" measures do not help - if you don´t have character enough to admit defeat against Mr Market. Most traders don´t have bad trading ideas, but BAD MONEY MANAGEMENT and RISK ATTITUDES. Worst attitude of all: I KNOW BETTER THAN "MR MARKET". Mr Market is ALWAYS right. And you are NOT "always right".
You should do scalping. Then you will become the dominator slaying the non-dominator and non-scalper.
