My strategies are focusing on survival first and then profit second aiming at 50% winrate at most but with a decent profit factor and sortino ratio while minimising maximum drawdown.
Every order has a SL & TP attached, often the TP is 10x larger than the SL. TP is rarely hit, because the system usually adjusts all trades accordingly.
As a retail trader, I have up to 1:30, but in general, I use only 10% of the maximum (1 - 3x leverage) per trade. For smaller accounts, I may use up to 30%, but as they grow, I will reduce the usage.
Since 1st June 2026, I have finalised the system architecture. Now, I own infinite amounts of strategies and can adapt to any specific needs. They can all evolve with time now.

This contest was an interesting one., and I have learnt quite many things from it. Taking a look at how other traders trade gave me some new ideas to experiment. I have adjusted all my systems, so that's about it. Next up, I will be trying prop firms as well to see how defensive my system can run. Lots of new findings this year, but probably that's all. Trading is a hard journey, and I am not rushing towards the end.

US public holidays weren't handled at all, so the system had left some trades in the contest. FX, WTI and GOLD are now updated to support skipping and flipping signals like what I experimented in May. It failed miserably last time, but I do notice some patterns with my eyes. The system can fail so perfectly at times, so the idea is reversing the signal at the right moment only. It is now updated to support all these new features, and I will start testing it from next week. Ideally, there will be at least one trade from each ticker per day.

The system seems to perform well even in M15 on US30 for the past few days. My next focus is also on US30 and NAS100 as the 4th final account. The system is meant to be generic from day one, but it can work better for certain tickers.

Moving towards 500 AUD, so the margin compute and usage will match the backtest better. Regarding "Too frequent deals may negatively impact copying results", the entry is designed to be a bit random, you may get better or worse fill than me but on average, it shouldn't matter that much. My account is only 1:10 for SpotCrude. Adjust the risk accordingly. 30% usage now is about 3x leverage, the max drawdown can hit 40 - 50% (13% is the base so 3x is 39% or more)

Updated the strategy to trade AUDUSD, EURUSD & USDJPY. GBPUSD & SpotCrude are removed, also slowly moving 155$ balance to WTI account to hit 500 AUD each. The new strategy will purely focusing on FX instead of doing a mix

A Gold version is also up and running since this week, but I won't put it up as a signal. I will also experiment with Copper and Silver to see if the WTI performance is truly ticker specific or generic as long as the underlying is more volatile.

Planning to make this version focusing purely on FOREX, since there is already a WTI version. Crude Oil dominates the return on this one, so it is a bit of overlaps

Working on supporting negative price due to the 2020 negative price incident. Monday this week, we took almost 3x the loss than expected. The bug should be fixed, but more testings until end of this year. Next year, if everything goes well, more fund will be used

Holding over weekends/days isn't expected. The system has been updated to avoid this. New config is also applied to further optimise on monthly return, sortino and drawdown. Currently, the system is very aggressive, more drawdowns is expected

Since 1st June, the signal won't be changed anymore, except for yearly optimisation

F.U.N.N.Y WTI Version. Extremely aggressive focusing on SpotCrude.a only. The drawdown will be significantly higher, but max deposit will be capped at 30%. Optimised for monthly return, sortino ratio, recovery factor and profit factor

After lots of backtesting and finetuning, the latest version is deployed. I have implemented an order splitter, so instead of 0.05 lot of SpotCrude, it will become 5 x 0.01 lot. This is preparing when the fund scales up. Max deposit load will drop to around 40% to reduce drawdown, but still expect 20 - 40% drawdown at some point.

New version is now deployed

Trailing + flipping didn't seem to work, the backtesting had some issues in the end. Overall, SpotCrude is the only valid ticker with over 4% profit on average every month. There are foundamental issues with the current system, but I will keep it open until the new version is done. Another new journey, but this time, I know what to do, no longer searching all the possibilities like back in 2024.

Trailing stop is now applied, this helps significantly in the backtesting, one of the top two boosters.

SpotCrude will now keep the double lot and having more priority, other tickers will revert back to regular margin usage. After some testings, only SpotCrude has sustained performance for the past decade. The equity change is due to a new deposit, the numbers could be larger than expected due to this change.
On average, I am aiming about 2 - 4% profit per month, but like I mentioned below, the drawdown will always be there. However, so far no tickers have truly reached 0 from my backtesting, they are all winning on average just less than SpotCrude.

The previous approach was too NAIVE, but I have figured out a potential improvement. A new version of F.U.N.N.Y is on the way with better margin usage as well. The win rate will still lock around 40% - 44%, and so far, SpotCrude is the only ticker with real edge. However, other ones are still valid, overall, it will still reach my goal at the end. Further optimisation will be applied per ticker, for example, we may block certain tickers on certain days, and flip only under the right condition. Drawdowns will still exist and be there all the time, this isn't what the current system can address sadly.

Further adjustments are required, simply having an inverse signal was a bad idea. I will pause the system next week to work on my new approach

With the signal flipping, the profit factor could reach above 2, win rate improves away above 50% and sharpe ratio can increase from 0.06 -> 0.18. However, this doesn't indicate future performance but for a reference purpose only. With a larger account like 5000$, the sharpe could improve significantly because the system is opening larger lots for certain tickers, but it is less a priority for now. Better profit factor, win rate and less drawdown is the main focus.

Wednesday, Thursday and Friday will now produce a counter signal. This aims to reduce drawdown while having more profit
