A tick is a price change so I guess you could only get an average value for ticks in 10 seconds anyway?

Why don’t you backtest on 1 sec then 2 sec then 3 sec etc and then whatever * sec TF gives you the same results / nearest result that got when backtesting on 29 tick TF … that is your nearest average in seconds to 20 ticks for that particular Instrument??

Indeed!

To obtain ticks quantity in 10 seconds, you can use the tick by tick chart, make sums of ticks received and reset each 10 seconds.

1) Do you know if PRT has plans to allow for ProOrder on tick-charts, and if so when? 2) Alternatively, would you know a way to obtain tick volumes when using a time-based chart? 3) Alternatively again, is there a way to transfer information from a tick-chart to a time-based chart that would be opened simultaneously?

1/ They are aware that this is a must have, but I don’t have any idea about ETA for this to be implemented.

2/ No, because variables are reset each tick received, so tick by tick chart is the only way to get the “ticks ratio” the way you want ..

3/ Not possible sorry 🙁
