before the coding begins. what is the overall goal with this data. are you trying to get the best price ( lowest spread at a fill) or using this data to determine where the market may go next? This information is useful but only if you understand what this data means and how you will apply to your egy. Basically we have three concepts here 1.) Duration of Tick ( seconds elapsed from last tick - ) 2.) Spread variation at each tick ( did spread increase or decrease) 3.) Size of tick ( how many pips( fractional ) did the last tick move) also do you have the source code of the indiors on your chart. if so gt; share!Originally Posted by ;
