Hi all there!The biggest thanks to the authors of this thread R4M and BD for a simple and reliable BD trading system and for its software solution as well as for the creative development of the trading system BDX .

My special respect R4M for the resistance to external interference which is constantly trying to knock down R4M from the General line of development.

And sorry for my English via electronic translator.

Finished reading the thread and work out BDX on a demo account ICMarkets via VPS.The first day had the same problem as the piko post# 5892. Per day of work AllPairsEA not opened any transaction.After changes in EA settings, trades started to open and the next day worked perfectly.

(%ADR) = 30 на М15 EURUSD
LotSize = 0.2
SL=1.8 %ADR
ТП=1.2 %ADR

The problem in the E A:
You cannot control the number of open positions.
For example, MaxOpenTrades=5 but opened orders equally 12!

The white lines are the sales made by the robot, the blue lines are signs but the robot did not take them.
Thank you

r4me, I know you don't like the word "repainting", but my observation on M30 chart is that the colour of last 3 Heikin Ashi bars keep changing with current price moves (btw which is not the case with Heikin Ashi indi that comes with MT4 - I know your discussion with other poster re. this, but apparently the one you use is somehow changing colours for the last three bars whereas the other one is not - just stating the fact :-)) which is affecting the signals and causing dots-arrows appear and disappear and reappear. And when this appearance / disappearance...
@Blackeagle -- yes, I've grown "touchy" about the word "repainting" and that's because so many people throw it around without understanding what it is or what causes it. But when repainting truly explains an observation then I'm fine with that.

I'm looking into your observations.

Regarding Heiken Ashi -- @KillerJoe and I are using the same code. The Heiken Ashi algorithm starts computing from the oldest bar and then moves forward. By default it starts around bar 5000 (or so) depending on how many bars MT4 provides the indicator. I start from bar 500 to save on computation -- especially with the dashboard and AllPairs EAs which may be computing for 28 pairs. Depending on how far back the algorithm starts computing then you start to see color changes. I don't know that the color changes would have much affect, but I'm looking into this now. Perhaps I will let it use all the bars that MT4 throws at it and just accept the CPU hit.

@Go5 -- I think it depends on the data. Normally it doesn't repaint. However, if there is a large spike then now I'm thinking the spike could pull the midline up or down such that when the indicator draws then it appears things have moved.

This morning (for me) I checked my accounts and saw lots of winning trades (trading mostly M15) -- but there were also some big StopLosses on GBPNZD and EURGBP. I've been looking into this and think I understand why. Both experienced very large spikes that caused my trades to hit their SL. Furthermore, the HMA transitions (backup Exits) didn't detect the change in direction in time.

I'm currently looking at adding yet another indicator to detect these situations -- it's a combination of momentum and RSI indicators I've used in the past. The tricky part is everything is a trade-off. I can further protect against spikes, but that may come at the expense of prematurely exiting trades that would have continued in the right direction.

Please keep the feedback coming -- this is great. This is exactly the type of posts I've been hoping for to help flush out the rough spots in the BDX strategy.

A spike makes it easy to see I guess, but the bottom line is that on a live chart the normal TMA behaviour is painted whereas in the tester (I used control points) the non repaint version comes up (which is what you want on the live chart also?)
I put little lines over the envelope extremes everytime a signal came up and after some move the channel was clearly displaced - this led me to run the tester.

Good morning Steve, please check my last two images that I uploaded in my previous 2 posts. There is a problem with the signals that are not in the indicator but the robot opened the operations.
And there are signs that are marked on the indicator but the robot did not take them.
Thanks Steve

Hello @Vicente -- I am checking and trying to understand.

And please understand that an indicator draws its markings based on historical data. That is, markings that occur in real-time may later change when an indicator is placed on a chart. This is the source of "repainting".

I think that the midline of the "non-repainting" TMA that I'm using may change -- i.e. repaint -- when an indicator is attached to a chart (due to the fact that an indicator uses historical data). This makes it appear as though the EA missed some signals -- even though it hadn't. The "signals" -- i.e. markings -- were not there in real-time but later get drawn by the indicator since it has the advantage of hindsight.

So, I may have to modify my statement that the Centered TMA may repaint in the vicinity of a large spike.

And I know the next question will be -- "Then why not make it non-repainting?" And the answer would be the same if someone asked why not make the ZigZag indicator non-repainting. Of course -- if ZigZag algorithm could be rewritten to be non-repainting it would have been. You have to understand the algorithm and how indicators work. If the ZigZag algorithm were to be modified to not repaint then it would need data from the future. Alternatively, it could be rewritten not to repaint but its lines would then be useless for real-time trading.

It always, always, comes down to trade-offs.

I didn't want to say anything until I could pinpoint my confusion as well, but I think you should do whatever it takes to match the indicator transitions to the standard HA as well (cpu hit and all) to prevent people from asking this.

edit: comparing charts side by side it seems like most the signals will be off by 2 bars at most...not a big deal if the indicator runs off color change alone.

Good morning R4M, I am, just thinking out of loud, kind of and trying to help to avoid that drawdown during the spikes. Wish I could understand inner working of the coding better and be of more help.
First thing come to my mind, that we use smoothed HA for exits for safety exits; is it possible that smoothed HA cannot react quickly during big spiked candles. Would normal HA used for entries be more responsive in case of spiking price action?
Do you think there a possibility to implement break even action when indicator "sees/touches" middleline, or it will be the same no action as with just closing the trade. Or may be for added safety make SL go to BE after fixed number of green pips, which may be adjusted in options according to time frame traded...if it was already discussed and i missed it...please just ignore the post.
Tonight I stayed awake as long as I could and stared at MT4 and watched how EA did its magic..it opened and closed lots of trades, some hit TP, some closed at middleline (at least MT4 showed closed price right at the middleline) and some positions missed TP by 2, 3 pips, thanks to increased spreads and went hundreds of pips against. If those "bad" positions were closed with one green pip or a few negative pips, the EA would beat the market...though its already doing it..
Thank you so much.

Checkout the screen shot above. I've developed 2 new indicators -- ZigZag and Fractals. The upper chart shows the ZigZag indicator alone and the lower chart shows the Fractal indicator overlaying the ZigZag indicator.

You can see from how the indicator renders that the ZigZag does a really nice job of picking out extreme prices where I should BUY and SELL. And the Fractals provide further confirmation.

Since the results of the indicator rendering look so nice then I'm thinking of combining these into a new EA. This new indicator should perform better than BDX because when the indicator is rendered on the chart then it becomes obvious where to enter BUY and SELL trades -- also, I can see where the best Exits are. I'm thinking the WinRatio could be close to 100%.

Okay -- hopefully, most of you realize I'm pulling your leg. It's to make a point. Someone, please, share with us what you think the point is.

These indicators look perfect in hindsight but it cannot be traded in real time, since they "readjusting" with every tick of data?

- It's obviously sarcasm, cause everything looks great in hindsight within charts; so even SMA crosses could make it that way. But in reality, it's a whole different story when you are trading in real-time, with mere ticks just "printing" their current price levels.
