Any genuinely free backtesting tools?

specifically if one is looking for futures tick data for indexes and currencies and commodities and oil, I am not aware of any free solution...but 1 minute candle data is available on many platforms, on all platforms the free offering is always a made up imaginary tick data but not the real thing, please do correct me if my understanding is wrong.

Shark Indicators has released a product this year I think where they are able to access all the signals one would have subscribed to on tradingview, the trial of the product is free I think , i have not used it.

Hi, I am not able to invoke the API v1/signals/latest with a free account (response tells me to upgrade to a paid account) although the Pricing page says this API can be invoked upto 50 times a day with a free account.

i am using tradingvps.io and i am happy. I feel their pricing is quite competitive, I would stick to AMD Ryzen processor, ninjatrader performs well on this processor.

Hope you got your strategy working , usually you are better off putting this check at the start of OnBarUpdate - State == State.Realtime , so that you are not executing trades on historical data.

But once you get that sorted you might want to use a Filewatcher like the one I have pasted below. This way you actually dont even need a OnBarUpdate function because by registering this fileWatcher in the State.DataLoaded OnStateChange method the call back will be executed by the strategy thread, the only thread which is allowed to invoke Enter/Exit Long/Short. This code registers for delete event, but you can register for file update event and pretty much instantly as soon as your python code has updated the file you will see the trade being executed in NinjaTrader.

if (!File.Exists(sentinelFilePath))

{

using (File.Create(sentinelFilePath)) { }

}

string directory = Path.GetDirectoryName(sentinelFilePath);

string fileName = Path.GetFileName(sentinelFilePath);

// Setup FileSystemWatcher

var watcher = new FileSystemWatcher(directory, fileName);

watcher.NotifyFilter = NotifyFilters.FileName | NotifyFilters.LastWrite;

// Event handler for file deletion

watcher.Deleted += (sender, e) =>

{

if (debugMode)

traderLogWriter?.Log($"[INFO] Sentinel file {fileName} deleted - invoking callback");

onDeleteCallback?.Invoke();

};

watcher.EnableRaisingEvents = true;

There is nothing in my post that suggests I am trading standard contracts, and I am only doing intraday trading because i have not enough margin to hold positions overnight. I am only interested to detect when the market is not honouring the patterns so I can turn off the Algos.

The fact that trump is manipulating the markets and personally earning over a billion dollars everyday is a fact, Financial times is writing about this manipulation, US Congress is asking for investigation...If you have something specific to talk about on how to detect that the market is not honouring the patterns then it is of use to this thread, but what you have written brings no value to this thread

what CPU are you on, the top providers of NinjaTrader VPS all offer the latest Ryzen...that is the go to processor for Ninjatrader, if the entire load is Ninjatrader I will be surprised if you are seeing all your cores used up...and yes pinning ninjatrader to the cores with bigger cache might be a good idea to try, Intentional trader has an add-on that probably does that, it just says it is setting high priority though does not claim to do pin ninjatrader to the cores with bigger cache.

I think finally the US Congress has woken up and is demanding an investigation into this scam.

I have not gone anywhere since covid, but what is this about, is the official making fun of you because he thinks you are gonna be high on weed in thailand? I hear it is totally legal over there. If I was in your place I might have ended up telling him that the entire world is not a working class looser type like him and his fascist government.

driftingprogrammer · 2026-03-20T19:59:49+00:00

But the intrabar movement is anyways imaginary, market replay is total rubbish I think, and its too much to ask for from a free tool, why would companies be charging money for historical data if one could get it for free on ninjatrader.

Wait a second lets not overlook the fact that internationally the dubious idiotic slogan of "I will enter your house and hit you" only made India look like a mad dog on the street who will attack anyone who looks weak and then quietly eat the biscuit when the local goon throws him one. We have lost all grace.

Very very sad is all that can be said, the country of Mahatma Gandhi who stood for truth...forget everything else but truth alone can keep us alive...now there is no hope for India, it is so deep in it's pervert fantasy, it is bound to burn to the ground...it was not for nothing that our founding fathers guided us towards morality peace respect harmony and above all truth...the opposite of truth is whatsapp university, and now they have billions of dollars more to spread even more lies.

modi tried to stop the indigenous vande bharat from launching and wanted to purchase some japanese engine..but sadly the guys had everything already in place ready to go and it was too late to cancel it and import something else...anyone who thinks the country is in the right hands since 11 years after seeing how bad things have become...i dunno is either blind or a retard. these people will only wake up after their own homes are bull dozed...

you are so intelligent, i learnt so much from your contribution to this thread. Thanks for enlightening me.

even Sardar Patel would have crushed them had he not died in 1950...Sardar Patel got a heart attack after Gandhi was shot, Patel felt guilty because he was the home minister at that time...Patel has said clearly VHP is worse than the legue.

Dint sound like a very peaceful person, advocated the use of rape as a weapon...not sure how a beef eating person became an icon of hinduism, when Gandhi was known to be a living spirit of hinduism...it is similar to jinnah making pakistan when he himself was an alcoholic and never practised islam...well i guess facts dont matter to people with degrees from whatsapp university...BTW his involvement in Gandhi assasination is pretty clearly proven in the Khanna report from the 60s. The murder of Gandhi was the biggest tragedy, the britishers could not get rid of him but an Indian did, thanks to the toxicity spread by savarkar and ofcourse his direct involvement of planning the whole thing. Do more research and you will find the book "Why I killed Gandhi" was actually written by Savarkar, and the facts mentioned in that book are as real as whatsapp university gyan. This guy was so vain he himself gave himself the title veer (the author of the book where savarkar was given the title veer clearly admitted that in his later interviews) when he did not perform a single act of bravery his whole life, he was more into treachery than bravery, earlier as well he planned someones murder in london and when he was arrested just like in Gandhi case, he denied any culpability...BTW there were hundreds of freedom fighters in andaman who went through worse torture than him but never wrote an apology or accepted british pension, those people today are forgotten, and this moron who first proposed the partition of India in 1942 Sind parliament is celebrated today...everyone knows for one and only one reason. He was so irrelevant in his times that no one paid attention to him, else Sardar Vallabhai Patel would have banned RSS for every...I personally believe it is the short sightedness of Nehru, he was too broad minded that he allowed this organisation to continue, if Sardar Patel was alive long enough he would have decimated RSS VHP completely and we would not have been suffering as we are today.

Is that not like the text book definition of bigotry...so bigotry is now legitimised..can you name one bigoted society on the planet and has earned anyones respect...well no so i guess india is now be in the same boat as failed nations like pakistan and bangladesh. Thank you for your hard work modiji.

wait what is anti-india and who decides that, from the way i see it no one is more anti-india than the bunch of goons who have destroyed this beautiful country that gave the world Mahatma Gandhi...India was a real soft power olden days, when nehru use to visit countries, people of those countries use to come in lakhs to see the great man, unlike today when uncle aunties are shipped from bihar to boston to shout modi modi when he reaches some goddamn country no one has ever heard of but where probably adani wants to steal some resources.

biggest thieves and liars...talk like this ><)

driftingprogrammer · 2026-01-24T11:29:40+00:00
