Hi,

As I said in the beginning of my post. I would like to know how to express Stop Loss / Take Profit as logics in stead of simple number of pips.

So for example, 

ExecuteMarketOrder(TradeType.Buy, SymbolName, TradeAmount, "BOT", 1.5 * PrevATR, PrevATR)

How do I replace 1.5*PrevATR (i.e my SL) with EMA20 crosses below EMA50.

Thank you

Hi,

You can use the EMA value as your position stop loss / take profit, ema20.Result.LastValue will give the latest value of EMA.

Yes. Thank you. I know how to express it as a variable. But how do I express it as a condition for Stop Loss. Because I cannot insert ema20.Result.LastValue < ema50.Result.LastValue into ExecuteMarketOrder(), can I ? So for example 

ExecuteMarketOrder(TradeType.Buy, SymbolName, TradeAmount, "BOT", ema20.Result.LastValue < ema50.Result.LastValue, PrevATR)

It shows these errors:

Error CS1502: The best overloaded method match for 'cAlgo.API.Robot.ExecuteMarketOrder(cAlgo.API.TradeType, string, double, string, double?, double?)' has some invalid arguments

Error CS1503: Argument 5: cannot convert from 'bool' to 'double?'

Much appreciated

Hi,

So you want to close a position when EMA cross happens? you can't put a logic on a position stop loss, to close a position when certain criteria meets you have to keep checking the criteria on OnBar or OnTick methods.

Hi,

Sorry. I'm very new to CTrader and API in general. In fact I only picked up pieces from Youtube and forums, here and there. Could you please elaborate more or give me a brief example on how to structure such criteria ? Thank you so much

Thank you amusleh. Quick question. How to I express "or" condition. I know that we use "&" for "and". But what if I want to express, for example, RSI smaller than or equal  to 70? rsi.Result.Last(0) =< 70. Thank you
