This is a variant of the MTF BB System only that there is no averaging down (except in the case of an extreme emergency, for example if one has forgotten to set the proper stops, with a precise exit strategy and rules in this case).

Scalping on 5 minute charts with a multi-timeframe setup (M30 - M5 - M1)

Works in trending, counter-trending and ranging markets.

Presently only tested on AUD/USD, will soon workout the details for other currency pairs as to specific parameters for trailing stops, best BB and SMA settings and possible entries.

R:R expected: from 1:1 upwards.

Some rules and indicators:

Rules:
Fixed trailing stop on entry at 15 pips distance and stops at B/E + 1 as soon as trade is more than 6 pips in the positive.
Only 1 trade open at a time, position size 1,67% of equity.
Only 3 consecutive trades per session (sessi side of the market). Maximum 10 trades per day.
Conservative aim of 1% daily.

Indicators:
Bollinger Bands (20)
SMA 34
SMA 200

Those are the basic indicators, however I also set Ichimoku Kinko Hyo as a visual complimentary aid.

A completely detailed description and manual will soon be available and posted at the Forex Factory forum.
