I am going to be honest as possible about this review since i never leave any reviews for any EA . I am a AI quant , a trader( for over 15 years ), worked for one of the Largest Hedge Funds in the world and currently run my own AI trading company but i have to accept that this EA is one of the best EA i have seen if not the best. It is Conservative, Accurate and both mathematically and statistically sound. For new traders remember that you will always loose a couple of trades . The goal is to have your Profit Factor always be above 3 every week or month ( 3:1 ratio) so long as you maintain a good level of StopLoss. Be conservative, there is no quick profits in actual trading ( NO Free Lunch) --NONE . Anyone telling you that their EA will make quick profits is scammer or failed trader and has no idea what actual trading looks like. Remember in trading , there is difference between being Lucky and being consistent with profits. This EA has very good entry timing logic and extremely conservative. Sergei has done great job on this EA and is honest about it. If you are new trader and you think you will not loose any trade , then get out of trading its not suitable for you. But if you can write your own EAs or get one that is actually based on mathematics not garbage indicators and is conservative then you will be ok. i have run the EA Live for 8 weeks with 23 Wins(20pipsx23 = 460 pips ) and 1 Loss ( 200pips x1 = 200 pips ) and then NetProfit = 260 Pips . This are just the default settings with no Grid and no adjustments. May be after another 8 weeks , i will update my review .
Rule of thumbs: Review your trading results after every 30 to 60 trades to gauge how well your EA is doing. Profit Factor Ratio must be greater than 3.0 on every new 30 to 60 trades.
NOTE: i don't know who Sergei is and have never met him or communicated with him apart from using this EA. My reviews are based on using this EA and my experience in actual Trading industry for over 15 years
Good luck
Update 3rd Jan 2021: The EA is Ok but you have to be careful. Most of the trades that are not closed within the first few hours have a very high chance of being a losses. The initial default mechanism for managing a loosing trade was " leave it open until it reverses by itself or take a loss at 200 pips". The updated version has added more settings but still be careful. The Backtested results (2010-2020) with default settings show extremely great results ( 1 loss in 10 years ) . I can 100% guarantee you that will not happen in actual live trading.
So is the EA good or not with default settings . Currently i would say the EA is ok if you know how to use it correctly otherwise you will feel then pain of losses and the EA holding positions for days or weeks. This is also the reason the EA , appears to be doing very well in backtesting . Note: you can't always be lucky in real actual trading to an extent you loose only 1 or 2 or 3 trades in 10 years. Rarely happens.
Until Next update. Stay safe
Update 14th Jan 2021 :
I have decided to discontinue trading the Perfect Score EA until i can figure out how to deal with the high risk of a bad trade that is left open until it closes even if the sentiment has changed . In intraday trading , you cut loosing trades and let profitable trades run with trailing SL and you also have to find the average loss of pips that indicates a trade has a very high probability it will be a loss. While the system will win a few trades in a row but one loss will tend to wipe out most of your profits. In Actual trading the EA seems to have an Average Win/Loss ratio of 6:1 to 8:1 . This means 8 wins for every 1 loss . In a perfect world that will be ok but in actual trading it does not happen majority of time .
The EA can be used for trading with careful consideration and monitoring otherwise its a little risky when it comes to having a loosing or bad trade. Some of the trades are open for days /weeks just to close in a loss. The author has added a few routine to try and rectify such issues . So i will let you be your own judge.
Great Logic behind this EA: 100% perfect match between official signal, EA and the backtest.
