In TradingView, I’ve integrated TradingView with Binance using alertMessage pinescript function. when Buying or selling condition is met, TradingView fires the signal to binance to place buy or sell order through alertmessage function automatically. The problem is that I only want to enter first met long and close at next short since the strategy I use is for the spot trading. not for the futures market.
So is there a way to ignore first encountered short entry and enter the next encountered long entry?

I’m struggling with the Pinescript as below. Instead of calculating the take profit/stop loss level based on the high/low of entry candle, it calculates the level based on the high/low of the next qualify candle. Can someone help me on this. Thank you.

I’m new to TradingView. 
I found a tradingview strategy, but no take profit and stop loss price. I’ve learned that on TradingView, follow FIFO signals. If the first open signal is always open, a new signal will show again, and the previous one is closed.

Create a Trading View custom indicator that automatically identifies the following chart patterns:

I have some small code but I can’t understand, please explain it, thanks:

I would like to use a dynamic comment in Pine Script strategy.exit using a string variable. Does anyone know if this is possible?
