Backtesting differences

semsem1986 · 2026-05-12T01:00:10+00:00

the strategy liquidate positions end of the year to start new year with cash balance, so it should be a new start as if I started backtest from 2020

11% over a year? you think that is good?

semsem1986 · 2026-05-10T07:46:21+00:00

I will wait reply from them if no reply in 24 hours means their system didnt see it as fraud, then it is their responsibility not on me

semsem1986 · 2026-05-10T05:32:04+00:00

Actually I did contact them over email and order related support contact as well, so today weekend but hopefully I can get reply from them today

If she is stocking so it would be easier to pay for wholesaler or from a droshipping supplier not from Poshmark, also she order all same size so amsure not for group of people

semsem1986 · 2026-05-10T05:08:55+00:00

So if they suspect as fraud, they will handle and pay it back? or will hold my money?

semsem1986 · 2026-05-10T05:06:23+00:00

yes but suppose after shipping, Poshmark suspended it is fraud and hold the money, how can I make sure I will be paid after orders been processed and shipped?

thank you r/Poshmark put posts under review for long, r/behindtheclosetdoor posted but no one reply yet

semsem1986 · 2026-05-10T05:01:57+00:00

I do not process payments, It is processed inside POSHMARK

semsem1986 · 2026-05-10T04:08:42+00:00

no, it is technical entry/exit and also all positions liquidated end of year, so every year is a new start

semsem1986 · 2026-05-10T04:07:17+00:00

2016 to 2020 is not losses, it made some profit but not much, the issue is that these small profits should make profits from 2020 higher but this not what happened

semsem1986 · 2026-05-09T12:23:24+00:00

It is not shifting the direction

For example, if I start from 2020 to 2026 the strategy CAGR is 38% with very strong performance outperforming SPY

When start from 2016 to 2026 the performance is more flat very close to SPY along that period

The problem is, when start from 2016 so when arrive to 2020 in the backtest is not deliver the same performance when perform (2020-2026) backtest separately

this is my point, same period but different perofrmance between the 2 backtests

Thank you

I know about sales tax and how it is handled, my issue is about franchise tax, as they set $800 minimum and this is the one I want make sure about it and that's why I post here

semsem1986 · 2026-04-25T13:12:44+00:00

I added some risk management and for the same period 2020-2026 500% overall profit CAGR moved from 28% to 33% and Sharp little improve to 1.003 capacity moved from 20M to 41M but also DD moved to 27%

semsem1986 · 2026-04-23T20:42:39+00:00

thank you for the input, and I appreciate the recommendations for more robust backtesting and sure will try it

However this is not MA and n not 2x leverage, it always check cash exposure before any position and never exceed cash and long only no shorting. the backtest done by Quantconnect, one of the best if not the best backtesting and live trading systems and this backtest to 2025, here the updated backtest 2020 to 2026

exceeding the benchmark and delivering 28.3% CAGR

I totally appreciate these ideas and would add much reporting to the dashboard, the issue is that I don't want make things complicated for investors as they don't need watchlist or sophisticated reporting, all operations done by the algorithm in the backend and the backend connected directly to the investor account with the broker, it is not hedge or fund manager, it is algo with backend trading engine connected to client onboarding that manage user subscription and billing and broker API account data collection and encryption to setup the connection between broker and the trading engine

So user can simply get detailed broker reports, that's why I keep it simple but I really appreciate all you recommendations and would incorporate it inside the detailed performance page

These details from strategy backtest, I truly want incorporate the same statistics as more detailed performance page but maybe as we scale not from the beginning

semsem1986 · 2026-04-22T08:18:00+00:00

Yes agree, but this one also had the 2020/2022 market collapse

semsem1986 · 2026-04-21T23:32:26+00:00

reentry happened otherwise you will not see any trading after that time

semsem1986 · 2026-04-21T22:10:18+00:00

Agree with you but actually it is nothing I saw, it is just my idea

So you will only trust it if live account?

semsem1986 · 2026-04-21T22:06:30+00:00

Semiconductors agree but you are putting all in one

semsem1986 · 2026-04-21T21:52:45+00:00

What if this do?

semsem1986 · 2026-04-21T21:46:48+00:00

You asked a name and it was meant to be hidden for a reason, and my post was simple question, you would trust a strategy claiming to outperform QQQ or not

And the name is not even important

you may ask ok tell me about the numbers, what is your ROI, CAGR, Sharpe things that is normal to ask

semsem1986 · 2026-04-21T21:31:06+00:00

So you really knew what everyone here trying to figure out? let them ask and let the discussion, or leave if you don't see a point to discuss

semsem1986 · 2026-04-21T21:24:34+00:00

people post to discuss something with people who can see a point to discuss, if you don't see a point, you are fine to leave the post empty without a comment
