Hi Pal,
Can you share the AFL for the Ehler's Squelch function...i found the
TradeStation code here
http://trader.online.pl/ELZ/t-pb-Squelch_Indicator.html
but hopefully you or someone else has converted it?
BTW, have you used any other trend-or-not indicators like ADX/DMI? If so,
how did they compare to Squelch?
thanks
-john

Subject: [amibroker] An effective stopping methodology - 3BSMA and powerSAR
stops
> Hi All,

> like all kinds of MA based stops, Gann's Rule of Eights stop, ATR
> based stops etc., I finally may have found a good one. It is based

> Trending and Trading Range. An instrument does not start a new trend
> immediately after ending the previous trend. It might go into a
> consolidation phase (Trading Range) before starting a new trend. The
> problem is to time this start of a new trend. Sometimes we have to
> wait for a long time indeed, thus if we enter the market too soon, we
> get whipsawed. To solve this problem, I came out with the
> following: Use a "mental stop" on day of entry at a reasonable
> distance from your entry point. Either an ATR based stop or a pivot
> point support/resistance based stop would suffice and exit only after
> 20 minutes has passed since your mental stop is exceeded and you are
> still losing. Use a 3BSMA stop during the initial stages (from next
> session after entry when the start of a new trend is still not yet
> confirmed) in accordance with the principle: Cut your losses short.
