Using calculate=eachtick strategy at stocks

[manitshah915]

hi,
My current strategy is using CALCULATE= each tick - i use it for NQ 03-24 instrument.

futures use TICK by tick methods.

----
But If i want to use this code for STOCKS like AAPL, META, GOOGL

then how this tick based code works?

I am confused, because stocks move cent by cent. Example- aapl will move from 119.21 to 119.22


--
so, what should I do?

Hello manitshah915,

Tick has two meanings here.
A tick can be a Last update coming from the market. The Calculation setting can be set to update for every Last market data update (or tick).
A tick can also be the minimum price fluctuation. The ES has a tick size of .25. A stock has a tick size of .01.

In historical, TickReplay is necessary to use Calculate.OnEachTick or .OnPriceChange. This requires historical tick data (such as from Kinetick or IQFeed, or imported from file).

so, if i want to use this on each tick code - for stocks

then I need to write down- on price change at calculate= section

am i right?

what happens,

if I use current- on each tick code at apple stock?

how will that behave?

will code check condition on each 0.01$ move?

Hello manitshah915,

No, Calculate.OnEachTick works the same for equities as it does for futures and forex.

"if I use current- on each tick code at apple stock?"

In realtime, or with TickReplay in historical, this will trigger OnBarUpdate() for every received tick (meaning Last market update), exactly the same as it would for the ES 03-24.

If you wanted to check the current price has changed by 1 tick, on any instrument type, you can save the current price to a variable and then on future bar updates check if the price is greater or less than the variable.

private double lastPriceSaved;

In OnBarUpdate():

if (Close[0] - lastPriceSaved == TickSize)
{
// price has increased by 1 tick exactly
}

if (Close[0] - lastPriceSaved > TickSize)
{
// price has increased by more than 1 tick
}

if (Close[0] != lastPriceSaved)
{
Print(string.Format("{0} | price has changed by {1} ticks", Time[0], (Close[0] - lastPriceSaved) / TickSize)); // print the amount of ticks the price has changed
lastPriceSaved = Close[0]; // save the current price to the variable for the next update to compare
}
