...first i will discuss about the volatility. i think that the volatility says nothing about if a pair is trending or ranging. i attached three pictures of different currencypairs. all of them are in Daily Timeframe...
Thank you for starting this important and stimulating debate. I do agree with you. However, IMHO Bob does not say that more volatile pairs have a better chance of trending but experience has shown that once in a trend they tend to have huge movements without a decent retrace. Large price movements (e.g. 1000 pips) without a decent retrace can have catastrophic consequences for his recovery system and range trading in general.

I may be totally wrong (which is not unusual) and would like to have your conclusions on this subject.

Kind Regards

i totally agree @astral. i for myself would not expect a decent retrace after 200 pip with a high volatile pair, but the characteristica stays the same. there are all waves around us. some are bigger (high volatile) some are smaller (low volatile).

i don't want to tell what is wrong or right. i don't want to put Bob's experience into questions.

i only want to discuss about it.

@steve you have to say if this would disturb this thread and i should open another one

With veryFastMA I mean just look at the present (not yet closed) candle and
take the Median price, (high+low)/2 with the low being the price touching the line.
In the EA this would be:
veryFastMA=GetMa(PERIOD_D1, 1, 0, MODE_SMA, PRICE_MEDIAN, 0);
And it does filter the touching points without closing too late.
Just to let you know, I like this idea and am adopting it in the coming update.

Well, as I'm a complete nerd regarding coding, if Steve says it's ok, must be ok! I was thinking too at a faster MA to apply some filter,but got no ideea how to translate that in code,hahaha...so,if the logic is correct, should let the trend move run. What about closing order condition? VeryFastMA>2MA(that's too early,I think,must see it on a chart), or close of candle above 2MA(speaking of a SELL)?

Updated version in post 1:

 

  1. Added Global Variables function so that BB knows which trades originated as range or trend trades. Understanding this is essential, so read'Stealth, criminals and Global Variable' in the user guide.
  2. Added the trend-trade exit feature that the mid-point of the current D1 candle must cross the fast MA in the wrong direction to trigger a trade closure.
  3. Added the ability to range trade at every tick rather than waiting for the start of a new candle.
  4. Added Caterpillar trade entry/management. Please read the Caterpillar section of the user guide for details.


I have added Cat to the downloads in post 1, for use in manual trading. I am far from convinced that it is working properly, so use on demo only.

Note: you can adjust the Cat lines manually; both bots will respond to your changes and look for fresh trades at the new price. I forgot to add this to the user guide.


How can I phrase this next statement to make sure people understand my intent clearly? I know.

It will be a bleedin' miracle along the lines of a Second Coming of a Cuddly Animal Loving, Newly Converted to Benevolence Antichrist if the implementation into BB is correct and works smoothly. All I can do is fight the bug-fires as they erupt.

Hehe. My user guide closing disclaimer is no different to my thread opening disclaimer. Both form a part of everything I publish here at FF.

I am simply trying to avoid being sued by titheads too ignorant and stupid to read my thread-starting posts and user docs, and who are too bollock-brained to realise that they trade at their own risk.

I understand your sentiment..
I used to be a silent follower of all NB threads and I really admire his patience when he again and again repeated everything he described in his docs to newbies.. Till one day when there was REALLY dumb member and he made NannigBob really angry: That kind of post he answered I never forget. He was mad at him. For the first time after couple of years everyday activity on his threads. In that situation someone posts: .."And thats why SteveHopwood locks all his threads"..:-)

I remember it was shortly before NB discovered you MPTM, so maybe that post began your cooperation..

Sorry for offtopic..:-)

Ok, the latest version of EA, I'm visual testing it atm and seems to work fine, Caterpillar is not opening orders, so I've disabled it in this testing, see pic...

P.S. Still trying to search for a better trend closing solution, in the attached pic, blue 5MA is median between 2MA and 8MA. Notice the spikes into 2MA and a bigger move that's fragmented into 2 small ones...5MA would have this avoided ;-) Just an oppinion, no offense...

This is a really useful post.

I am going out this afternoon. Later, I shall add an optional median moving average as part of the exit strategy. I shall also add a 'Trend-trade exit' section to BB's inputs list, so that users can easily find and select the exit options they wish to use.

It is easy for coders to create your own exit strategies:

 

  1. create a variable in the general declarations section, so its value can be displayed on screen for user feedback.
  2. add the call that gives the variable a value to void ReadIndicatorValues()
  3. add a call to ReadIndicatorValues() to start() and init() underneath the calls to TrendDetectionModule()
  4. add code that considers the value of the variable to void LookForTradeClosure()
  5. add code to void DisplayUserFeedback() that displays the value of the variable. This step can always wait until you are ready to publish your experiment; I find it helpful to have confirmation that my indi call is correct.
  6. name your filter and add a Usexxx boolean to the (soon to be created) trend-trade exit section of the inputs. Remember to code the optional use of your filter into LookForTradeClosure().



Re the Caterpillar function sending no calls, there is code that is correct for the stand-alone version but wrong for BB. I have fixed this in the post 1 update.

I use a concept which worked for me on EU from the beginning of 2011 and I think this might be the solution of the last problem of fantastic NBs system: Exits.

an example for sell trend trade.

-BB sends two sell orders. one with no TP (a recorvery trade) and one with TP 10 pips
-in this moment BB sends also about 20-100 (user preference) sell stop pending orders
-all pendings have 10 pips distance between them and all have 10 pips TP
-Tp of the first sell trade is opening price of the next pending sell stop
-Tp of the sell stop pending order is opening price of the next sell stop pending order and so on.. BB makes a grid of pendings in whatever range.
-that way we are pocketing all pips in the trend till the trend reverses into a buy
-If this happends the trade without TP will cover the loss of the last opening pending sell stop order which causes a drawdown by reversal

I setup pending orders on EU manually and prefer the beginnig entry on whole number (f.e. 1.43300 with tp 1.43400, next pending will be 1.43400 tp 1.43500 and so on..)

pros:
-we gain pips from the whole trend and if the price goes far enough from its entry we can stay much longer in the trend.
-we can manuly close the recorvery trade which bring us additional pips if we feel that trade reverses
-or we can let it run till the price goes back in between the entry point and the highest/lowest price point of the trend where recorvery trade balance the last trade of the trade which causes DD.

cons:
we open double lots which causes double problems in recorvery mode (not yet implemented in BB) or double loss when SL is hit.

Hope this makes sense

Updated version in post 1. Please read Trend trade exit strategies:from Specific Trend trading inputs in the user guide.


There could well be bugs in the code.

Might be a nice ideea...practically we gain every single pip of the move.
Meantime, please enlighten me, Steve, Caterpillar is suppose to open orders where we drag the lines, or it shouls act by itself? Either way, it's not working, even if tested alone, even if tested in Bigbob...at least for me.
Anyone else having the same problem?

P.S Right now I"m testing BigBob only with trend option on a H4 chart, seems really interesting...but with other MA values. Don't blame me, I'm curious!;-)

Wow, what can I say.
I was so excited last week, to see the results of Nanningbobs work reflected in the closing balance of my demo account on Friday.

I am even more elated to see Steve's contribution. Thank you both.

Reading the user guide I see that Global variables sometimes go missing without notice on the metatrader platform. It is our responsibility as traders to keep a weary eye open for this and to insert it should this occur.

Since I, like many, are trading about 15 pairs or more it can be difficult to keep checking that GV's are in place. I was wondering if it is at all possible to include in the code, a check to see if there is a GV for the pair if it has a trade open and, if not, to send an alert notifying the trader of the problem so that it can be rectified.

Better still, could a missing GV, once detected, be replaced by the code?

Wishing only to contribute positively to this thread I hope this is not a silly comment.

I am looking forward to the coming week.
Thank you

i see that the variable: MinTriggerCandlePipsMovement is a fixed pip-value. would it be wise to use a %age value? because every pair has its own volatility. you may think that i have a vola fetish.

Cheers
