I see sc.TickSize in the ACSIL. However, I do not see the PointValue for the Instrument on the chart. Is there an ACSIL reference to obtain this. I am trying to do the following: float dollarvalue = PointValue * TickSize * ticks * contracts. |

Here is how I approached the contract values in case anyone else needs some help: //prototypes float GetTickSize(SCStudyGraphRef sc, SCString attachedInstrument); float ConvertTicksToDollars(SCStudyGraphRef sc, int ticks, int contracts); float GetTickValue(SCStudyGraphRef sc, SCString attachedInstrument); float GetTicksPerPoint(SCStudyGraphRef sc, float tickSize); float GetTickSize(SCStudyGraphRef sc, SCString attachedInstrument) { float tickSize = sc.TickSize; return (tickSize); } float ConvertTicksToDollars(SCStudyGraphRef sc, int ticks, int contracts) { float dollarValue = 0; if (ticks > 0 && contracts > 0) { float tickValue = sc.CurrencyValuePerTick; float tickSize = sc.TickSize; dollarValue = tickValue * ticks * contracts; } return dollarValue; } float GetTickValue(SCStudyGraphRef sc, SCString attachedInstrument) { float tickValue = 0; //float tickValue = instrument.MasterInstrument.PointValue * CustomChartBarInterface.TickSize; //PointValue = currency val of 1 point move $20 for nq, $2 for mnq //ticksize = 0.25 4 per point //mnq 1 tick $0.50 //nq 1 tick $5.00 //.25*20 = $5 tickValue = sc.CurrencyValuePerTick; return tickValue; } float GetTicksPerPoint(SCStudyGraphRef sc, float tickSize) { float tickPoint = 1; if (tickSize < 1) { tickPoint = (float)(1.0 / tickSize); } return (tickPoint); } |

In your function `GetTicksPerPoint(SCStudyGraphRef sc, float tickSize)` you are dividing by tickSize. If the tick size somehow ends up being zero, you'll get a division by zero error. That would probably crash your study. It's worth handling that situation. Date Time Of Last Edit: 2024-06-10 00:20:17
