The very simple recipe IF you've got a 1000$ to risk for the fame...
1. Pick a volatile pair which seem to be all set for a directional turn
2. go all in
3. Pray that it turns before hit margin call...(could be end of game here)
4. If flipped ride it, if you select good the move could/should last 3-4 times
5. Relish your extreme hard return%
1A. Alternative: high risk martingale, with the remaining things.
Contest, especially those short term, and even more so the demonion ones are a fantastic bait for the broker, tricking ppl in that it is really easy to gain 100s of percent in a short time, and producing them deposit out of greed than they can manage to lose.
These contest egies dont continue, and hard to repeat.
Without high risk, there's absolutely no high return (maybe not in short time such as days/weeks anyhow).
