Create a tiny PHP Script for Data Analysis from a .CSV

Dear Freelancer, i am looking forward to receiving your proposal for the following project: We do already have a small php script that creates a big file with data from all available currencies on a trading platform that looks like this: date; high; low; open; close; volume; quotevolume; weightedaverage; currency 01-03-2016 08:05:00; 0.00013114; 0.00013114; 0.00013114; 0.00013114; 0.00207504; 15.82313617 0.00013114; 1CR Your tasks would be these: 1) Adapt the script so that it saves these exact same information, but instead of saving it into one big csv file, it should save the data into one small csv file for each currency. the files should be named like this CURRENCYPAIRNAME_DATEOFDATAMINING - ex. [login to view URL] into the directory "separate_currency_csv" on the server. 2) Write an additional small php script that analyzes the data from all the currency csv files in the directory "separate_currency_csv": GUI: In the browser we should have 3 textfields to type in numbers: - "TradingVolumePerCurrency" ... Is an amount between 0.00 and 1000.00 bitcoin - "ProfitTakingFactor" ... Is a Percentage between 0.00 and 100.00 (please show that as info next to the field) - "Tradinginterval") ... Is the Interval in minutes which has to be divideable through 5 ... means that the minimum tradinginterval is 5 and it can only be traded in timeframes of a multiple of 5 ... ex. 15 minutes ,60 minutes but not 17 or 63 minutes (please show that as info next to the field) And 1 button: - "Run Analysis" ... starts the script WHAT THE SCRIPT DOES: Go through all lines of data in all the .csv files in the directory "separate_currency_csv" and only use the value from the column "close" to calculate anything. this has to be done separately for every single currency and the taken profits from every single currency have to be added up into $totaltakenprofitsinbtc 0) consider that the script holds an amount of of that currency .. this is considered the tradingvolume of that specific currency that is beeing processed right now consider that a "trade" has happened before you start with processing line one ... trade: means just reset $valuechange to 0 and add the value of $valuechange to $totaltakenprofitsinbtc consider that this script should simulate that it is been run only once every $tradinginterval minutes ... this means that a trade can only be made at exactly these times and not in between (like for example: trading can only be done exactly every 35 minutes) 1) in the variable $valuechange add the differences of the closevalue from previous line to closevalue from currentline [currentlineclosevalue - previouslineclosevalue] (of course this can as well become negative numbers) ... for the first line do [currentlineclosevalue - 0] calculation 2) when $valuechange >= $profittakingfactor, then execute a trade ... in other words when the value of that currency has gone up in % >= than specified profittakingfactor then execute a trade (means reset $valuechange = 0 and add the value of $valuechange to $totaltakenprofitsinbtc) THE RESULTS IT SHOWS: Take Profit Earnings: 0.13 bitcoin Data for the server will be given to you after we have assigned the project to you. Thanks and cheers, Robert
