Mansfield Relative Strength Trend

'Stan Weinstein' developed an indicator called Relative Strength which compares the relative strength of a stock with the associated index (in this case the S&P 500).

This indicator combines the relative strength with Weinstein's stage analysis.


The indiacator was made for weekly stock charts only!


BUY & HOLD Conditions (green):
1. Mansfield Relative Strength is above the zero line
2. Price is above the Simple Moving Average (30)
3. Simple Moving Average (30) is rising

SELL & HOLD Conditions (red):
1. Mansfield Relative Strength is below the zero line
2. Price is below the Simple Moving Average (30)
3. Simple Moving Average (30) is falling

It is recommended to end the trade when the trend changes.


Default index is S&P 500, but you can change the index in the settings if you want.

Please always remember, there is no holy grail indicator!

Notas de prensa:

I was told that in the book of Weinstein (page 25) he describes he uses a weighted 30-week moving average (WMA).

So in this new version 2.0 I fixed that.
There is a boolean option to choose if you like SMA or WMA.

From the book:
This makes the MA more sensitive to current activity and helps it reverse direction faster. The drawback to their weighted average is that it leads to a few more whipsaws..."

Personally I like the SMA, but this is not in line with the real strategy.

Upper indicator: with WMA
Lower indicator: with SMA


Hope you like it

Best regards
