Why I Built MYTH

For a long time I treated backtesting like flossing. I knew I should do it. I told myself I would. I didn't.

The reason was simple. Backtesting felt slow and the market felt fast. Why sit and replay old candles when there was a live move right in front of me. So I traded, I read charts, I formed opinions, and I trusted that my screen time was teaching me something. Some of it was. A lot of it wasn't.

The wall

The day it stopped working I was sitting in front of a separate candle replay tool with roughly twenty Excel files open. One file per idea. One per market. One I had started and abandoned. The replay tool was good at showing me price. The spreadsheets were good at holding numbers. Neither of them knew the other existed.

So every time I wanted to answer a basic question, I became a clerk. Pull the trade from one place. Type it into another. Tag it by hand. Hope I used the same label I used last week. By the time I had the answer, I had lost the thread of the question. And half the time I didn't trust the answer anyway, because I knew how sloppy the data entry had been.

That is the quiet trap. The work of recording your trading gets so tedious that you stop doing it honestly. And once the record is dishonest, every conclusion you draw from it is just a feeling wearing a number.

08.08

There was a specific day. I keep the date for myself. It was the day a loss landed that I had no clean way to explain, because I had no clean record to explain it with. I went looking for the pattern and found a pile of half-filled sheets and screenshots in a folder named "review" that I had never actually reviewed.

I wasn't angry at the loss. Losses are part of it. I was angry that after all that screen time I still couldn't answer a simple question about my own trading. I had memories. I didn't have evidence.

Building it for myself

So I started building the tool I wished I had. Not as a product. As a way to stop being a clerk.

The first thing it had to do was hold my history without a fight. Bring in the spreadsheets I already kept, in whatever shape they were in, and turn them into something structured I could actually query. No reformatting marathon. No starting over.

The second thing was replay that remembered. I didn't want a chart in one window and stats in another. I wanted to step back through a trade candle by candle, see what I saw, and have that sit in the same place as the numbers.

The third thing was honesty by default. If recording a trade is easy and consistent, you do it. And once you have a few hundred trades recorded the same way, you stop arguing with your feelings and start reading your own data.

When it became a product

I used it. It worked on me. I stopped guessing about my own patterns and started seeing them. And it turned out the problem wasn't mine alone. Every trader I talked to had their own version of the twenty files and the folder named "review."

So the private tool became MYTH. The mission didn't change when it became a product. It is still the thing I needed on 08.08. A place to keep your history, replay it honestly, and let your own documented trades tell you the truth instead of your memory.

That is the whole idea. Master your Trades. Honor the MYTH.
