DOSI: Daily Open Strategy Improved

Quoting dokopy
I suggest trying this strategy as well. It is on the daily charts and gives more signals. https://www.forexfactory.com/thread/...-candle-system
Thank you for the suggestion.

The 217-page read, and even post #1 is rather intimidating. Quickly skimming over that thread, it looked like it needed a lot of discretion and manual judgement, or am I wrong? Obviously, only a strategy with clear black/white rules can be automated in an EA.

Can you point me to a post in that thread that compactly summarizes the strategy?
Guys, you are so funny.
DOS is really great system and straight forward, and you seek "idi..o..tic" systems instead?
That guy "mastermind" uses TP of 2 pips in his published account, do you know that?
Hi Mate:

Can we add two input parameters "Profit Lock in Pips" and "Profit Lock Trailing in Pips"?

It works like Trailing Stop to lock in profit ( for both Single and Basket Trades ), as to prevent profits slipped away or dragged longer in trades.

For example, TP is set to 100 pips, and we set Profit Lock in Pips 60 pip, and Profit Lock Trailing in Pips 10 pips.

With that, we know our single/basket trades will have at least 60 pips in profits once price reached that level, and if should price divert again, we have at least 60 pips in profits locked, and, move on to next trades.

Or, if should price move in our favor, we will trail the Profit Lock in every 10 pips, until either the TP is hit or the Profit Lock is hit.

I hope my explanation is clear.

All in all, the EA is great, the strategy is good, what I trying to do is to maximize the profits and reduce the drawdown on portfolio basis.

Again, thank you for your valuable time and contribution.
Excellent idea

I'm trying a stupidly simple system. The problem is that without EA I have to wait for inputs at night. I pulled the indicator from the thread. I used PT from DOS settings. I put SL at the nearest peak in history. I chose the most moving pairs I tested in DOS.
Please excuse the bad English via Google Translate.

I agree with you. DOS only requires good pairs with good drawdrown to reduce risk. Nothing more. Even in lower TF’s it’s reliable.

At this point I’m testing only two TF, 1H and Daily. At the moment I prefer don’t say anything about settings because it requires too much study and I’m on a 5% of the total test. The conclusion at the moment, for me, its the strategy in a few pairs it’s lot size dependant. So my opinion it’s control the risk very well.

A few posts ago yoriz shows that in three different scenarios the curve is growing because of averaging down strategy. Maybe the MM its the key, but its my opinion.

and also, this is backtest, lets do the work on forward.

I have uploaded version 1.45 that does stricter input validation to avoid problems during Optimizer runs. Please give that a try! {quote} To reduce the lead-in time needed before the first trade is made, I enable trading already when have encountered only 1/10th of NrBarsLookback bars instead of waiting for the full NrBarsLookback bars. But with value 1 this effectively means 0.1 bars, which is rounded down to 0. So the minimum value is actually 10, not 1. Nonetheless, I don't expect such short lookbacks to be useful, since you need to collect enough...

Hi Mate:

I hope this message will find you well.

Mate, can you add an input parameter for Magic Number for the EA?

I am demo testing the EA with D1, H12 & H1 time frame on one same pair GBPUSD. I believe without proper different magic number, the EA might mess up the trades.

I hope you got what I meant and the situation I am trying to describe. Let me know if I got it wrong.

Mate, thx for your time.

Regards,
Bill

Sure. I have uploaded version 1.50 which has a configurable MagicNumber input parameter.

Thanks for the suggestion. Not sure I fully understand what you are trying to do. If you are at exactly 60 pip profit, what should happen? Should the EA then start trailing at 10 pips distance? So worst case you would get 60-10 = 50 pips profit. How is this different from a trailing stop?

Can you explain more what should happen when price reaches the 60 pips Profit Lock?

Add two input parameters: "Profit Lock in Pips" and "Profit Lock Trailing in Pips"

Should the EA then start trailing at 10 pips distance? So worst case you would get 60-10 = 50 pips profit. How is this different from a trailing stop?

Hi mate: This is exactly how the EA work. When it reaches 60pips in profit, the EA will start locking the profit 60-10 = 50 pips in profits, at least.

Then, if price move 10 pips further, then it will trail and lock 50+10 = 60 pips, till the price hit the TP, or, the Profit Lock.

It is same as Trailing Stop, but in this case, only trailing when in profit. We locked the profits and trailing it.

I hope I explain it well. Let me know if you need move examples.

All in all, I would like to have the EA not to have the profits slipped away, reduce the time on the market, reduce the risks & drawdown.
It is called trailing step.
Hi Mate:

I demo test the EA today with a number of forex pairs and different time frame.

1 weird thing I found out today is, the EA can be removed automatically, gone missing from the chart.

I noticed the problems, thought it was something wrong on the MT5 platform.

I reinstalled the platform and the same problems occurred, at least I managed to catch it.

My computer setup is top notch and up to date in terms of CPU and memory RAM.

Here are the codes for your investigations:

In addition to the errors above, I managed to catch these lines of error moment ago:

2021.10.11 10:29:26.783 Trades '1051031422': failed market buy 0.01 XAUUSD [Position doesn't exist]

I reattached the EA again to the chart(s), loaded it with set file, then the EA opened and closed trades as normal. Very normal.

Then, maybe an hour or few hours later, the EA will gone 'missing' in self-removed mode.

Yes, that is by design. If the EA encounters a very unusual error, it will stop trading and remove itself from the chart to avoid making invalid trades.

These errors suggest that the internal bookkeeping of the EA gets out of sync with reality. It thinks some orders were closed by sl/tp while they were not, or tries to update an order that was closed?!

This is normal, and not a problem with your MT5 platform. This is the result of the EA abruptly terminating itself without cleaning up used memory.

I can not reproduce this problem in the Strategy Tester with the settings you provided which makes it hard to debug it. I will open a demo account to see if I can reproduce the problem there.
I do most of my testing in the Strategy Tester, and therefore did not notice the weird behavior when switching the timeframe of the chart the EA is attached to. That would cause partial(!) reinitialisation of the EA. This could be the cause of the "resetting open order is not allowed." error.

Uploaded version 1.55 tries to fix this behavior (as always, see post #1 for the link). In addition, as a fail-safe, the EA will try to close all open trades whenever it encounters a fatal error. Note that I can not guarantee this always works flawlessly, because upon a fatal error things can be unreliable preventing the EA from closing trades.

Hope this resolves some/all of the problems.
Some users like to examine a wide range of entry criteria and therefore make the EntryStrategy input parameter also part of their optimization runs. Having RandomDirection in the selectable options obviously does not make sense, so I moved it to the begin of the range (now option A), to enable optimization runs using only options B .. D. Beware when using previously created .set files that options have changed!

However, in my opinion this strategy does not really seem to have an "edge" (see post #41) and purely relies on averaging down. This means that optimization runs should focus only on finding good TakeProfitPips, MinScaleInPips and MaxDrawDownPercent, to make sure the averaging down part of the EA is tuned. I don't think it is useful to try to optimize the entry criterium, as this will only be curve-fitting to lower the drawdowns in simulated years but you will definitely encounter them in live trading.

My advice would be to optimize only the input parameters in the "Exit Signal Settings" and "Recovery Settings" sections, and then do many random runs to estimate what the risk of ruin is, and what are realistic lot sizes. For that, I added the RandomizationSeed input parameter. To verify your optimized settings, you could select the RandomDirection entry strategy and have MT5 "optimize" only the RandomizationSeed input parameter (range between 1 and 1000000000). That way, the strategy tester will go over many different scenarios so you get a feel for what drawdowns you can expect on average and in the most extreme cases. This can help choosing the right lot sizing.

Does this approach make sense?

I agree. There are some pairs that makes good DD, about 3-7% with minimum 85% winner trades in 10 years at least. Of course the most important parametres to “play” and find good dd and good balance are: Pips Body Size and TP. There are some pairs that if increases lotsize, good DD goes to 35-40% DD. So the key is search good pairs with its own parametres.

im only testing it on daily tf, but Im sure that in lower tfs there are good opportunities
