How to lose 1.2 million dollars and burn 300 subscribers

I see it the same way, there is simply no upside of losing for him, not with losing subscriber base, not with losing other trading opportunities, and I know about at least one...
What one should learn from this, as a trader, or as an investor?

Everything is prone to fall. Even the best traders have worst days.
Something that - maybe- a prior stat can't predict.
Technical or emotional reasons, really finest matter.

A trader can use some sort of stop, preferable maybe some automatic one, that takes decision some point out of his hand, when emotions likely to run high, and the temptation to over ride the original loss limits is most likely. Yes, traders are humans, and not without weakness. But knowing and accepting those, opens up a chance to prepare for them.
Never a secret that I like equity SL.
Can define risk tolerance and can set things that at that point an EA or script take the decision from me, and close all.
Admit, since trader has a chance to tamper this, it is not 100% fail proof, but usually if there is some discipline, there will be less likelihood to change on the fly. Also, ultimately, it is the trader's fund, right?

Investors point of view is different.
He doesn't have most of the time the same insight into trading. See a position on, but not necessarily know the reason it opened, or the expectations on it.
Have a promise from the trader he follows about low drawdown, but what that number may be? Who can tell, really?
Well, the investor should be able to tell!!
And can, by so often investor is just as much a gambler than the trader he subscribe to!
And lazy, most investors are lazy!! They can just the same implement that equity SL!!! And define their risk and loss tolerance. Plus effective take out the decision making at some point from the trader's hand. Ultimately, the trader may recover, and they stuck in a loss vs a gain in a point, but better losing 10-20% of capital, than being down -40-80% and top of the emotional rollercoaster, with the only things left is a prayer not to crash and die, but with less and less rational means to stop this point.
The dice has been cast!

There is a middle ground of course, some trade copiers, or PAMM accounts will let both parties to define and set this risk amount, $ or % equity. If one truelly an investor, or size, not 100$, but at least couple 1000s, it is a must.
Cos traders he emotional. A fact. Many had lost his head, in fact I think most likely anyone who trades has such experience themselves.
Best one can do is prepare for it.
I know I do, the same way, using equity SL script, so, on main account if I am slow, or hesitant, or stubborn to close a trade, it is my risk, but any other connected account will automatically execute an equity SL, and I am disciplined enough for that to not tinker those setups.
Loss is part of trading and it happens all the time!
But one could and should be able to define the maximum!!!
Traders and investors alike!

Happy trading!

developer of Abby was dishonest and tottally unskilled.
He fail walkforward test his method during bear markets, enough long history and boosted his strategy look better only long trades and multiple !
"nothing to do building position." just fixing bad entry.

MQL5 makes way too easy people loose they money, because lack of exprerience and skills to read greeks/stats and understanding.

Without coding skills everybody can create similar strategy less than hour, using free ea builder or ninjatrader. example using multiple moving average crossover.

I only wrote : "I have a suspicion." I did not say: I have a certainty.
I only wrote:" am I wrong ?" It was a simple question , so you could simply answer "YES".
Instead, your arrogant , intolerant and offensive response makes me think thay I've touched an uncovered nerve.

PS : " friggen mind , lazy , stupid , etc." : say that to your mother and to your close relatives.

I agree with everything you say.
He was just wildly stabbing at the market which was basically going in one direction.
You are absolutely right when you say that the subscribers are are just as much gamblers.
I believe that many of them are hoping for blind luck.
The proof of that is that I offered to analyze any .csv trading history for anyone who cared to submit it to me.
It turns out that nobody wants to look behind the curtain. Thar be Dragons!!!

MQL5 should keep bad performing strategies pages; so people can see the past.

There is a survivorship bias on their website.

It does, just go on the site and look at it......

While the trade history of any trader is visible after signing in, it is not exportable to be analyzed.
Please see the reply from their CS. I've tried twice.

You can just go through that history manually and see the classical pattern of hiding and stockpiling loosing trades till the day of reckonging.

I would call it gambling based on hopium combined with some sort of Martingale.....
Any equity curve that is too smooth to be true will most likely be too smooth to be true.

Even if history is hidden....doesn't matter.....if you know how it looks like you don't even have to look at history to know exactly what's going on.

You may very well be able to get a general sense of the trading style of a particular trader by tracing some trades from his history and following a few entries and exits with some mental gymnastics.
Ironically you will also almost certainly be right when you conclude that there is a lot of stupidity and luck hiding behind those smooth Equity Curves.
But I can assure you that night turns into a bright day when you see every trade of every pair plotted on their appropriate charts.
And this is only half the story. The Excel spreadsheet gives you the full story on all the data points I previously listed.
I just recently analyzed what I thought were the top dozen or so signals on MQL5 with the intend of subscribing. I came away thoroughly depressed.
Almost all systems were Martingale and Grid based even when the trader said that this was not the case. Sadly, some of them had subscribers galore.
About the only approach is to invest whatever money you can afford to loose in the hope that you can withdraw your original investment, and get a free ride there after. Keeping in mind that this should be done quickly. Also taking the subscription cost in to consideration, you are probably looking at close to 4 figures.
It is very distressing when you look at a long trading history of more than a year for instance, and you see a trading pattern that could be considered aggressive but acceptable, but you then see periods of outright insanity where money had to be deposited to keep a low DD and avoid a margin call. What is to say that this is going to work next time. But then again who is to say that it will not work?
Once I had a Croupier in Vegas tell me that he has seen Red come up 48 times in a row.
Anyway...I would love to convince you. so pick any MT4 signal on Mql5 and tell me. I hope I can prove my point to you.
