ABOUT ENGTMK
An engineer’s mindset.
A long view.
I’m Tamer. I work with technology, build systems and invest in the markets.
Across more than 20 years in technical roles, I have learned to ask the same questions: how does this work, where can it fail, and what evidence would change my decision?
That way of thinking also shapes my investing. I have traded publicly on eToro since 2011, through opportunities, mistakes and periods when patience mattered most.

A PRINCIPLE I RETURN TO
Discipline in execution.
Freedom in outcomes.
I believe in being disciplined about preparation, decisions and execution, while remaining flexible about where the path leads. Strong systems create better outcomes, but resilience comes from adapting when reality changes.
IN THE MARKETS
A clear process.
An open mind.
I primarily trade liquid U.S.-listed equities and ETFs. I use supply-and-demand zones to plan swing entries and custom Python screeners to identify momentum and breakout opportunities.
Each idea needs a reason to exist, a level that invalidates it and a position size that makes sense. I consider the portfolio as a whole: several different tickers can still carry the same underlying risk.
My planned risk is no more than 1% per trade. That is a sizing rule, not a guarantee of the eventual loss: gaps and execution can change the outcome.

The habits behind the process.
Define the downside
Set the planned exit and position size before committing capital. Consider how the position fits the rest of the portfolio.
Allow time to work
Wait for the conditions the plan requires. Cash is a valid position when the opportunity does not justify the risk.
Review the evidence
Record the decision, examine the result and change the view when new information warrants it.
WHY I SHARE THE WORK
Make the reasoning visible.
ENGTMK brings together my research, lessons and practical planning tools. I write about the forces moving markets, the reasoning behind portfolio decisions and the habits that help me stay consistent.
The useful record includes losing periods, quiet months and ideas that need revising. I want readers to have enough context to assess the approach for themselves.
