I am looking for a PHP developer to build REST API's script that integrate with an exchange. For a particular market, the script needs to report a count of fluctuations from price_1 to +/-pct_1-5 in a day . So, the script will work like this 1) Input into program is market, price_1, pct1, pct2, pct3, pct4, pct5. Pct1 -5 are percentages 2) Go through all the trades for yesterday and calc the total number of times the following happens for pct1, pct2, pct3, pct4 and pct5 a) that the price went higher than (or equal to) pct1-5 and then returned to price_1. I will also need the average vol of tokens sold at pct1-5 (i.e. positive pct) b) that the price went lower than (or equal to) -pct1-5 and then returned to price_1. I will also need the average vol of tokens sold at -pct1-5 (i.e. negative pct)
