How to see real time value for RSI?
I just see if RSI is now above/below 50 in real time.

Zorro is a trading robot. It does not have real time chart windows. For a real time RSI curve, a conventional platform is better, for instance Ninja Trader.

If you want no chart but only see if RSI is above/below 50, you can use Zorro - it can display the real time RSI value in a slider. If you want that, I can show you how.

I just want to use a incomplete current bar like MT4 to trade my way.
Is there any manual about it?

Sure, here: http://manual.zorro-trader.com/trade.htm

Call enterLong(f), where f is your function that uses an incomplete candle for finding an entry. This function is called whenever a price quote arrives. The price() functions work as before, they are just in the middle of the candle now. When the entry condition is met, let f return with 2 to execute the trade, otherwise with 0.

Don't try this with normal strategies, though. Many indicators have wrong values when the last candle is incomplete, and using them for trade signals is not a good idea.

Thank you, I will try.

Just my 2 cents: I mentioned the problem of the 'senseless' close[0] value already in Steve Hopwoods forum where he agreed that this was one of the problems of his EAs.
