What was going on here?!Įxamining the recorded data I discoverd that most of the time the stock price fell right after buying shares and recovered after a few cycles. But running the two scripts made me loose money. For the volatility I had to look at the source and generated a list for that as volatility seems to be quasi-static. For the forecast I looked back ten market cycles and subtracted that from the current price. Second I copied my old trading script and replaced the API calls for forecast and volatility. The idea behind this was that the slope of the price of a stock is stable over a longer period and I would need to collect the prices over time to tell whether it is going up or down. Btw you could also try to make money in the casino.įirst I made a script to simply record the prices of all stocks. Now I had to write a script for trading without having 4S Market Data TIX API Access - even without having 4S Market Data Access at all.

Of cause you can still hack manually but you will not gain money from doing so. Having done all BitNodes at least once I started doing the challenges and when it came to BitNode 8 the challenge says: 'Destroy BN8 without purchasing the 4s market data.' I thought: 'Okay, no problem, I can do the manual hacking thing once again.' Unfortunately someone removed that feature since I last did BN8. So I wrote a script for manual hacking, let it run while growing and weakening the target, bought 4S Market Data after hacking enough money and wrote a simple script for trading at the stock market, finished BN8 and moved on to other BitNodes. The terminal can be scripted and the documentation also provides an example (Injecting HTML in the game). When I first played BN8 I discoverd it was possible to gain money by manual hacking.

Otherwise you might end up tearing your hair out. StockHist.js records prices, stockBB2.js buys and sells shares.

Update: The jouney continues! Some hints on Reddit and digging into bitburners source are going to improve the script (todo) tl/dr A journey to make some serious money without having 4S Market Data in Bitburners BitNode 8
