The best algorithmic developers aren't just programmers - they're traders who code.
I develop and code custom trading strategies, automation tools and custom software across multiple platforms and languages, including TradingView (Pine Script), MetaTrader 5 (MQL5), Python and other modern development frameworks.
Looking for a quantitative developer role.
I can turn trading strategies into fully functional systems.
Extensive experience with Linux (Gentoo, Debian) and Unix systems (FreeBSD, OpenBSD)
I’m available for projects.You can ask for me directly on Freelancer
How Observation Changes Outcomes :
In quantum mechanics, when light (or electrons) passes through two slits, it creates an interference pattern on the screen behind them.
Each particle seems to go through both slits at once, existing in a superposition of all possible paths and the resulting pattern reflects the probabilities of where the particle could land.
If you try to measure which slit the particle goes through, the interference pattern disappears.
Observing the particle forces it into a definite state - it goes through one slit or the other.
The act of measurement collapses the wave function and fundamentally changes the outcome.
Before you check a trade, it’s in superposition.
From a statistical perspective, your trade has a probability of winning or losing based on your system but you don’t yet know the outcome.
The trade is evolving naturally, just like a quantum system.
The moment you look at it, your observation collapses the “trade wave function” into a definite state - good or bad, winning or losing.
That observation triggers an emotional reaction — stress, fear, or overconfidence—which can cause you to break your plan, over-leverage, or revenge trade.
Just like in quantum mechanics, the act of measurement affects the system.
If you hadn’t looked, the system would have continued evolving naturally and you would have followed your plan without emotional interference.
This analogy mirrors the quantum concept perfectly - observation changes the outcome, not because the market changed, but because your interaction with it changed your behavior.
In other words, checking too often destroys the natural probabilistic outcome of your system, just like measuring the slit destroys the interference pattern.
The trade itself hasn’t changed; your observation changed how you interact with it, which changes the outcome.
Final Thoughts:
Traders, you know what I’m talking about — in a demo, you can leave your strategy untouched for days, weeks, even months.
The moment it goes live, you start checking too often, micromanaging your trades, and suddenly your observation is affecting the outcome.

Pro15.30 days. Mean reversion and the trend strategy, Side by side, running untouched for 30 days

Two strategies can both win when run side by side because they exploit different market conditions, producing gains at different times that compound over the same period.
Jason Smith
You have seen results of Pro15 trading a mean reversion strategy over 60 days. (magic 55)
This is Pro15 trading over 30 days but in Trend mode (magic 66).
Its a dual system EA. That can trade mean reversion or a trend strategy

Pro15 has been running fully autonomously for 8 weeks without any intervention, holding positions overnight and through weekends when necessary.
Using its mean-reversion strategy, this bot is now available for sale at $1,000.

You can use it for both and i will try to get it ready for today. Just testing this latest feature
Jason Smith
As an experienced trader, this is a very high-end tool, and only 2 demo downloads is an absolute insult.
Jason Smith
I’m not sure if this is just a gimmick or a genuinely useful tool, as it hasn’t received many comments or reviews yet.
I’m making this a free product, as of now and any feedback would be greatly appreciated.
This is the only one of its kind on MQL5, and after seeing many traders on the forum ask for more timeframes, I came up with this idea to address that need.

If you purchase Pro15, let it work. Avoid the urge to micromanage every trade.
Trust in the strategy and parameters you’ve defined.
Take Breaks:
Step away from the screen to maintain mental clarity. Automated trading ensures you don’t need to monitor the market constantly.

Trading can be exhilarating but also mentally demanding. Pro15 not only helps automate your trading but also supports a healthier trading mindset by reducing stress and emotional decision-making.
Jason Smith
Pro15 creates its own support and resistance lines which can act as stop loss and take profit levels.
These lines update automatically as new daily highs and lows are formed. The Aqua, HotPink, and White lines can be toggled on or off and will update dynamically, while the Yellow line can also be toggled but remains static at the daily open.
The green and red entry signals update automatically as new daily highs and lows are formed.

Why is this not on the market place if you sell it? Seems pretty sus if you ask me.

Overnight gold price action was almost exactly the same as yesterday.

If you genuinely have an edge like that — repeating overnight structure, near-identical behavior day to day — then you’re sitting on one of the rarest advantages in trading: predictable conditions combined with high-probability setups. Add to that a disciplined framework for entry, exit, and position sizing, and you can turn what looks like minor repetition into a systematic profit engine
