I am at learning stage therefore even it may so simple i could not write a formula for the following case, Thanks in advance any helpful comments, The aim for the formula is to create a moving stop loss - start win indicator, Instead of using Close values of the prices, the system should use a little bit more smoothed values, thus i would like to use 3 periods exponential moving average for the price signal as Mov (C,3,E). Moving Stoploss should have a trailing nature and should act also as Start Win indicator. Therefore i prefer to call it Moving StopLoss StartWin indicator. MSL-SW MSL-SW should always follow the MovA (price signal) with 2% of intervals ; MSL-SW lower than the MovA (Uptrend) Condition A When MovA is increasing MSL-SW should follow the MovA and should be equal to 98% of MovA. When MovA is unchanged or decreasing in comparison with the one day before value, MSL-SW should stay at the same value. Crossing down of MovA with MSL-SW should be considered as SELL signal. (Stop-loss) and MSL-SW should be upside down as described in the following condition. MSL-SW is higher than MovA (Downtrend) Condition B When MovA is decreasing MSL-SW should follow the MovA and should be equal to 102% of MovA. When MovA is unchanged or increasing in comparison with the one day before value, MSL-SW should stay at the same value. Crossing up of MovA with MSL-SW should be considered as BUY signal. (Start-Win) and MSL-SW should be upside down as described in condition A. An example for the indicator...

Hey hayseed thanks for your interest, however if we plot Mov(C,3,E)*0.98 and Mov(C,3,E)*1.02 we would get an envelope..Which aLways following the 3 periods of exp. Moving average one edge on the upper side and the other one at the bottom... The curve obtained should be some how clever and when prices are goes down or stay same (horizontal) it should be stay at the same level and therefore it would give us a STOP signal. The opposite situation when prices goes up it would give us a START signal... Ahhh I know it is terrible... IS there anybody for thyis challenging formula ?

hey nuisance.... talk about a fumble, somehow missed the ""MSL-SW should stay at the same value.""" part of your post, even after reading it several times ..... sorry about that..... and thanks patrick for the recovery...... using patricks code gives very good results.... i created an expert advisor to test .... its easy to see the accuracy when you plot both your stop and a 3 exp moving average in the same window..... nuisance long stop loss

{put in your buy code, bc} bc:=C>Mov(C,10,S); lvl:=Mov(C,3,E)*.98; If(bc,lvl, If(ROC(C,1,%)>0,Max(lvl,PREV),PREV))

---

nuisance short stop

---

bc:=C<Mov(C,10,S); lvl:=Mov(C,3,E)*1.02; If(bc,lvl, If(ROC((Mov(C,3,E)),1,%)<0,Max(lvl,PREV),PREV));

just playing here with expert advsor to test bullish trend

---

Fml("nuisance long stop loss")<Mov(C,3,E)

---

bearish trend

---

Fml("nuisance long stop loss")>Mov(C,3,E)

---

that might not be exactly what you were hunting but should get you a little closer , nuisance..... and thanks again patrick......h

Thank you so much guys.. This is not 100% the same what i required, but it works anyway... :)
