About “Synapse smart EA MT5"

Quote from the official MQL5 page

Synapse smart based on the latest neural network algorithms that allow high-precision forecasting of future price fluctuations. The EA uses the algorithm we developed for setting the SL and TP levels, considering the levels of support and resistance, channel width, and extremes of the price chart. The advisor does not use grid, martingale or any other unsafe strategy. The advisor has a money management system that allows user to set both a fixed order size and calculate it based on the size of the deposit or the maximum allowable drawdown on one order. The Expert Advisor is pre-configured, so it is enough for the user to install it and use it with default parameters. EA also has a system of tips that allows the user not to make a mistake when changing settings. Limitations of the EA: only two currency pairs – EURUSD, AUDUSD, maximum order size – 0.1 lotsTimeframe – H1.

Description of the parameters:

  • Instruments — List of currency pairs;
  • Order size calc. method — Selection of order size calculation method;
  • Order size — Order size in lots;

Trading of “Synapse smart EA MT5"

It is an EA produced by the same company ( as the TardersMind EA included in the portfolio, and the basic behavior including the display format of the dashboard on the chart is the same. Perhaps the basic logic before implementing the neural network is different, but I don’t know the details. Also, the authors in MQL5 are different, so they may be working as a group of programmers.

Short-term backtesting on EURUSD and AUDUSD

  • Account: NZX Zero (ECN) (NOZAX)
  • Initial Balance: $1,000
  • Parameters: Initial Setup
  • Period: 1 January 2020 – 31 December 2022



So far, so perfect.
However, the comments (evaluations) on the official MQL5 website are not good … Long-term backtesting yields the following profit and loss curve: It’s a little suspicious…

Since this EA is optimized using the “neural network algorithm", the possibility of “overoptimization" cannot be ruled out.

Long-term backtesting on EURUSD and AUDUSD

  • Account: NZX Zero (ECN) (NOZAX)
  • Initial Balance: $1,000
  • Parameters: Initial Setup
  • Period: 1 January 2008 – 31 December 2022



Parts that have not been clearly optimized, such as those enclosed in a good red frame, are detected. If the basic logic before optimization works to some extent, these traces should be difficult to detect, so it is difficult to use them.

At the time of testing (February 20), this EA seems to be [Version: 2.4 Updated: 27 January 2023], and we cannot rule out the possibility that the latest good performance will be due to the update.

Instead of suddenly including it in a portfolio, I would like to continue verification by forward testing it separately on a demo account.
