I just came across this expert about a months and a half ago.
Downloaded the version from the site and set it up on demo at Tickmill.
First bad sign was that the expert wouldn't backtest. Why would someone disable backtesting on an expert that doesn't need multiple pairs for its work?
I asked author the question, but Konstantin went all vague, referring to some "defence mechanisms" and "dll dependencies" that make backtesting impossible. Sounded really weird as there are many experts out there, well protected and with dll dependencies, backtesting just fine...
After a couple of weeks of trading I did the analysis and the strategy didn't seem very solid: multiple tiny profits and a few chunkier losses, although trending up, smelled of a Demo Grail kind of strategy: an EA that leverages the lack of slippage and delays due to execution with liquidity provider.
I chatted with the author again, sharing my concerns and asking him if there's an option to test it in live, with min lot. He refused to accommodate the request, so I sourced the "fixed" version from one of the forums, the one that worked on real just like it was on demo.
I set it up on my live with min lot of 0.01 solely to verify the performance.
For another two weeks the expert was working on my live account and, as expected, it was making losses, where his demo brother was making profits - entering at the same point, but with minimal slippage involved, it couldn't close in the same tiny profit and was falling back to stop loss.
It is worth mentioning that I have a VIP account with Tickmill, my commissions are minimal and trading conditions are rather perfect. All MT4 instances are running on the beefy VPS with a latency less than 1ms.
Last Friday I was going through my VPS setup, cleaning and grooming, when I noticed the number of open deals in my trading view starts growing quickly.
I couldn't believe what I was seeing at first: every second there was a new order, each one 10 times bigger lot than the previous one.
It took me few seconds to react and by then I had 6 deals open: 0.01, 0.1, 1, 10, 100 and another 100 lots.
Those orders didn't have any comment or magic number associated with them as if someone opened them manually.
I immediately shut down all terminal instances that were autotrading, switched to the local instance and close all open order - as you can imagine, with substantial loss.
Further investigation showed those deals appeared in the logs on the MT instance that was running PRO VSA.
Interestingly enough, it didn't log anything in the expert log, just the common one.
It was rather obviously a sabotage by the author that somehow had discovered I was using it on real account.
Funny enough, the author pinged me in Telegram next morning, calling me names and claiming I "paid for being greedy".
I asked him, where did those deals come from and he first was all about "the person who hacked the EA did a mistake, messing it all up".
Which can't be the case by any stretch of imagination: for an advisor to start booking these deals without magic and comment, every second, multiplying the lot by 10 every time - someone should have wrote this code in the EA in the first place.
In addition, it was working just fine for two weeks.
When I presented those arguments, the author first suggested that "random portions of the algorithm being executed because the protection has detected the misuse" - which is terrifying idea on its own, suggesting he has embedded the algorithm in the EA that can wipe your account in seconds if for some reason it believes something isn't working as it should.
Just to remind you, the official manual suggests to restart the MT with the advisor running every week "to restore the connectivity with the server".
After our discussion was published on one of the forums, he has came up with the new idea: he was saying there is a hidden parameter in his code, called "hard scalping" - the one that is turning this draining algorithm on, and the hacker that messed with the code must have switched it on.
Which, again, doesn't add up, as the EA was working just fine for two weeks.
So my inference would be that the author has a button to drain your account.
This is a wild guess, a speculation - but an alternative explanation, suggesting there is an algorithm in the EA that may decide to do the same isn't much better really.
here's my myfxbook, for anyone interested to take a look, search for Rigal, system called Scalpers.
You want to filter by magic number (there are two marked “PRO VSA (proforexea)”) to see the two-weeks long curve trending down.
Select "manual" in magic analysis to see those USDJPY deals of 211.11 lots in total.
Just wanted to warn anyone to steer clear of this scam: the EA itself is not good, and the author seems to be dangerous psychopath. You don't want to hand a keys to your account to this kind of person.
