Mntiwana you see? There is just no room for normal discussion.

But for the sake of argument, let's stay focused on the issue and try one of his "recommended options" RSI(5) on his trading timeframe (5M) chart and see what happens. I will add also RSI(8) and RSI value I would choose (21). GBPUSD sounds like a good pair (his own recommendation again) for divergences with its many peaks during the day and "smoother waves".

As you can notice, there is no "lag". I also identified and drew some major divergences during the London and NY session according to this basic rule:

"The highs or lows you identify on the indicator MUST be the ones that line up VERTICALLY with the price highs or lows."

If we were to follow this rule, the lowest RSI value (5) would fail twice while RSI(8) would make it but on two occasions wouldn't connect properly (line crossed peaks on indi). RSI(21) would do it right all 3 times. We can obviously skip the rule, but then the discretionary part of trading kicks in and that is something that can't be taught.

In case someone would say "it was during sideways market with no volatility", the area on the picture has range of 86 pips and ADR(30) on GBPUSD is 89. So slightly below average volatility.

I'm not going to draw any conclusions other than the fact that I acknowledge the usability of divergences now more than when we started this but I still find them laggy for my risk appetite (I prefer tight SL trades). I'm also retracting my words that they are unreliable below 4H, they can be used up to 5M if scalper is willing to widen his stoploss (or trade without confirmation).
