Hi insane,
I’m known as a debater, it helps me understand both sides of a discussion. Can you clarify as to the statistics to which you are referring? I’ve never seen a “lost trade” so can you explain what that means?
Everything below Daily is just a smaller scale and the trading needs to be scaled down appropriately. I can scalp 2-3 pips all day on the 5min timeframe. i would never look to take a large target (more than 10 pips) on a 5 min chart. They are there and can happen, I’ve had some 20-30 pip winners on the 5 min chart but that’s not what I’m looking for. I look to scalp 100pips a day in about 60-90 mins.
If I was trading the h4 or daily then I would be looking for incrementally larger take profits prob 20-100 pips, but that is not what I focus on. I would also use much larger stop losses. It’s all relative. That’s why I’m confused about the statistics you are using … I trade forex and the e-mini and stocks. Forex is the most consistent for me. But that doesn’t mean that anyone can’t specialize - You need to pick the TF that works for you. Timeframes are all related. it takes five 1 minute candles to build a 5 min candle. Twelve 5 minute candles for the hour, etc. There is always price action on every candle on every TF. You have to create a system that is profitable that fits your style. If you don’t have an hour or two to sit and work through 5 min candles and watch, then yes you prob need to go to a larger TF and place and forget.
As for the 20k investment, I can say 15k of the investments did not pay off, but the last 5k is more than gold. 
I’d love to share info, let me know what info you are looking for … Have a great day!
