Requirements and Limitations in Making Trades

Tables below show calculation values that limit the conduction of trades when opening, closing, placing, deleting or modifying orders.

To get the minimum distance to StopLevel and freezing distance FreezeLevel the MarketInfo() function should be called.

Requirements.

Correct prices used when performing trade operations.

Order Type	Open Price	Close Price	Open Price of a Pending Order	Transforming a Pending Order into aMarket Order
Buy	Ask	Bid
Sell	Bid	Ask
BuyLimit			Below the current Ask price	Ask price reaches open price
SellLimit			Above the current Bid price	Bid price reaches open price
BuyStop			Above the current Ask price	Ask price reaches open price
SellStop			Below the current Bid price	Bid price reaches open price

The possibility of deleting a pending order is regulated by the FreezeLevel parameter.

StopLevel Minimum Distance Limitation.

A trade operation will not be performed if any of the following conditions is disrupted.

Order Type	Open Price	StopLoss (SL)	TakeProfit (TP)
Buy	Modification is prohibited	Bid-SL ≥ StopLevel	TP-Bid ≥ StopLevel
Sell	Modification is prohibited	SL-Ask ≥ StopLevel	Ask-TP ≥ StopLevel
BuyLimit	Ask-OpenPrice ≥ StopLevel	OpenPrice-SL ≥ StopLevel	TP-OpenPrice ≥ StopLevel
SellLimit	OpenPrice-Bid ≥ StopLevel	SL-OpenPrice ≥StopLevel	OpenPrice-TP ≥ StopLevel
BuyStop	OpenPrice-Ask ≥ StopLevel	OpenPrice-SL ≥ StopLevel	TP-OpenPrice ≥ StopLevel
SellStop	Bid-OpenPrice ≥ StopLevel	SL-OpenPrice ≥ StopLevel	OpenPrice-TP ≥ StopLevel

FreezeLevel Limitation (Freezing Distance).

Market orders can not be closed if the StopLoss and TakeProfit values violate the FreezLevel parameter requirements.
StopLoss or TakeProfit orders can not be modified if StopLoss or TakeProfit values violate the StopLevel parameter requirements.
Pending orders can not be deleted or modified if the declared open price violates the FreezeLevel parameter requirements.

Order Type	Open Price	StopLoss (SL)	TakeProfit (TP)
Buy	Modification is prohibited	Bid-SL > FreezeLevel	TP-Bid > FreezeLevel
Sell	Modification is prohibited	SL-Ask > FreezeLevel	Ask-TP > FreezeLevel
BuyLimit	Ask-OpenPrice > FreezeLevel	Regulated by the StopLevel parameter	Regulated by the StopLevel parameter
SellLimit	OpenPrice-Bid > FreezeLevel	Regulated by the StopLevel parameter	Regulated by the StopLevel parameter
BuyStop	OpenPrice-Ask > FreezeLevel	Regulated by the StopLevel parameter	Regulated by the StopLevel parameter
SellStop	Bid-OpenPrice > FreezeLevel	Regulated by the StopLevel parameter	Regulated by the StopLevel parameter

Hi Fernando,

Are  freeze and stop levels changing while a position is open, or are they constant? In other words, do I need to run SymbolInforInteger(_Symbol,SYMBOL_TRADE_FREEZE_LEVEL) every time I change SL (or TP), or could I compute it just once and save it in a global variable?

thank you
