i built an expert advisore with pending orders but every chart the expert creates many pending orders maybe 20 per chart, how do i create only one pending order for each chart, i attach the ea.

i suggest you don't work on renko they all lose in 99% modeling quality test.
because of the range period.
it is most of the time ranging so you've got one or two renko bars for each direction.
it makes the expert lose.
if you created a renko ea check it with renko fxt builder on tick data and you'll see they all lose.

i was wondering how can i prevent slippage

it doesn't open any trades.

thank you i'll try

i want to create an ea that when an order takes stop loss it takes another position, for example, if I opened a buy order and it hit stoploss, the ea will open sell trade, and vice versa.
i tried check type last loser block, but the ea didn't open any position, what to do than?

i have a problem creating a london breakout ea because all of my london breakout indicators, don't have buffers.
the eas i built don't open positions.
how to solve this problems, thanks in advanced.

thanks for your reply i'll try

I've created an ea from an indicator with two buffers, i put the
indicator on a chart and it clearly shows arrows.
but the ea i created 0 buffer for buy 1 for sell , but the ea doesn't open trades.

how to open 5 pending orders at once.
