Many reasons.

1. Many months (or many years) ago many professional people said: asctrend system and asctrend indicators are nothing. They can be used on D1 and W1 timeframe only. The other (professional) people said: they are useless even for D1 and W1 timeframes. Absolutely useless.
Not one person said. Everybody and everywhere in the forums. It was as axiom.
So now it is not axiom because asctrend can be used for scalping even.
It was proved.

2. The other reason. I do not have time to trade as Nina for example. Because I am admin and I am managing elite section and so on. I am not able to. I can design some systems and somebody should continue.
M30 timeframe is interesting.

3. There is no unique system just for everybody. The traders are selecting the systems according to the character, personality and so on. So if we have many systems really working so the traders will have a choise.

4. There are many good systems without real statements. For example: person may say - i have good system please help to create EA. Good system - good statement. No statement - no system. And no system - no problem. Where is the good statement for good system? Nowhere? Just a words? No statement - no system. Almost always like this.

5. I am acting as admin. If nobody is developing something so I should do it. I can not sit all the day to see how the other people are posting. I want to do it as well.

I will stop on m30 timeframe with this system.
And will develop digital systems (continuing the digital filters thread) and some other systems.

Of course the main goal is the EA creating.
