No issues here…..
As a guess…..check the following:
If you’ve recently updated TWS….(or even if you haven’t)
In TWS:
Go to “EDIT” -> “Global Configuaration” -> “API” -> “Precautions” and make sure the option “BYPASS Order Precautions for API Orders” is ticked…..That’s happened to me recently (i.e. I upgraded TWS and this was unticked and was stopping orders being sent)…..

(having the opposite effect then?)Honestly, I think it is market related, as the DD’s occur when the rest market is crapping itself and all trading systems tend to cop a slap across the face during these times, you can’t avoid this…. If we take a quick look at the 2008 stats during the GFC where the Drawdown is the most…. and compare DUAL Stretch Shallow vs DUAL Stretch Deep.
The numbers during this period are slightly higher %Win, AvgWin% and lower AvgLoss% in the DUAL Stretch Deep variation. So small differences there, but definitely a lot less trades in the DEEP stretch variation as well… less fills as a result of a lower BUY Limit price etc, so where not suffering ‘death from a 1000 cuts etc’ burning up cash etc.
Deep Stretch Stats
Shallow Stretch Stats
When I put the system together I focused on the 2021-2022 period as I wanted to try and get a system that actually made a decent return (it was bugging me and I wanted to find something that actually worked for this period
) and then once I had that, went further back in the sample period.I only tested the 1990-2005 period after I got the system to this point….. and I believe Nick mentioned in another post that the mid 1990’s is/was similar to the past couple of years in terms of market conditions. So when I tested that period, the system with the DUAL Stretch option, performs well/acceptable/passable etc…..Additionally, the year 2000 was another year where the returns were pretty amazing e.g. +400% and +500%…. these stats are what the backtest came back with…. (if only I had been trading the system back then
)I’m also using the same lookback period for my entry filter and ranking method…. so fairly consistent and simple from that point of view….
Monthly Stats
Single Stretch
Dual Stretch Shallow
Dual Stretch Deep
The system entry is based on volatility and uses volatility to determine current market conditions and which stretch to use within the dual stretch option. It has a Min/Max price entry condition and a single Indicator entry condition…. very simple.
FWIW, I use a MSI laptop.

Whatever you get, providing it’s one of the better known names/brands and reasonably priced, should be fine…..
One thing to make sure of is SSD hard drive….. you mentioned 1TB hard drive in your post, but I’m not sure if this is SSD or HDD….. so whatever you get in the future, ensure it’s SSD….. AB / RealTest will perform MUCH faster on SSD.
Looks like you’re considering a laptop with at least 64gig ram (mentioned in your journal post)….. nice!!!!
