FXCodeBase.COM: Forex Chart Indicators and Development

Update Oct, 05 2010. The indicator performance is improved and additional features are provided for in-strategies and in-signal usage.

The indicator is a port of Metatrader TrendLord indicator.

Trendlord indicator shows the trend direction. A green bar means uptrend and a red bar means down trend.

A green bar appears when TrendLordFunction is above the previous value and a red bar appears when it's below the previous value.

Important! The indicator repaints one bar back when direction is switched. So, the signal and/or strategy will show the signal two bars back against the displayed value.

The function is
LWMA(LWMA(close, N), SquareRoot(N))
where N is the indicator parameters.

Can you add a MA timeframe confirmation?

Something like this.
Your request is not eloquent at best,
and It is difficult to decipher it.

Sorry about that...
1. I download the new file and it will not show up under my strategies.. check it on your end..

2. After looking at other strategies I think I was asking for was a MA Filter based on a timeframe..This may be what you did, once I can load it and look..

So a Buy trade would be as (1 min chart)
Trendlord green
if price above 1hr 50 MA
Buy

Trendlord green
if price below 1hr 50 MA
do nothing

Trendlord red
if price below 1hr 50 MA
sell

Trendlord red
if price above 1hr 50 MA
do nothing
